• Miniature discoidals down to .050” OD

• Filter arrays

• Custom style capability

• High voltage designs available

• High temperature designs available

• Square tubes for surface mount applications

• Lapped feedthrough capacitors

Discoidal Feedthrough Capacitors: Ideal for by-pass and filtering applications with a low inductance construction suited for high frequency applications. Their low profile and rugged design is an excellent alternative to ceramic tubes. Tubular Feedthrough Capacitors: Small and lightweight with high dielectric strength and impervious to moisture and contamination. Feedthrough capacitors have a uniform insertion loss over a broad spectrum range and are ideal for multi-pin connector applications. Tubular Pi Capacitors: Similar characteristics to feedthrough capacitors in addition to a narrower transition between the pass and stop bands, effectively stopping high frequency interference without affecting desired frequencies and providing filtering of noise content close to signal content. SMPS (Switch Mode Power Supply) Capacitors: Deliver lower equivalent series resistance, lower equivalent series inductance, lower ripple voltage, and less self-heating when compared to other capacitive elements. Planar Array Capacitors: Offer faster assembly time compared to stand-alone chips, discoidal, or tubular capacitors. They also have a low profile and are capable of meeting various geometric and electrical configurations, making APITech’s planar capacitors the new standard in EMI suppression applications.

High Voltage Chip Capacitors: For applications with high voltage requirements. These capacitors can withstand higher voltage and lower leakage characteristics than typical surface mount filters.

• Commercial and defense applications

• Power supplies

• Converters

Feedthrough (FT) tubular capacitors are ideally suited for by-pass and filtering applications. Due to the cylindrical design, the capacitors will have uniform insertion loss over a broad frequency range. This struc-ture yields a low inductance when compared to conven-tional wound capacitors.

Solid FT capacitors have no internal electrodes and find their primary usage in low cost applications. Multilayered FT capacitors have a higher capacitance to volume ratio and are ideally suited for greater filtering at lower frequencies. Multilayered FT capacitors are also designed for applications where source impedances are high and sharp attenuation rise is critical.

Feedthrough Circuit

Features• High ratio of capacitance to volume


• Small, lightweight, reliable, high dielectric strength

• Impervious to moisture and contamination

• Uniform IL over a board frequency range

• -55°C to +125°C operation are achieved with no voltage de-rating.

• Outer terminations feature a nickel barrier and final metal layer, typically silver

• Commercial and defense applications

• Power supplies

• Converters

Compared to feedthrough tubular capacitors, Pi tubular capacitors have a much more narrow transition between the pass and stop bands. Pi capacitors are effective in stopping high frequency interference without affecting necessary frequencies immediately below the stop band.

Similar to feedthrough tubular capacitors, Pi tubular capacitors can be designed with a solid or multilayered configuration. Solid Pi tubular capacitors are more cost effective, but limited in capacitance values. Multilayered Pi tubular capacitors can cover a wider range of capacitance, while still maintaining the mechanical strength of a solid Pi tubular capacitor in a similar case size.

Dielectric CharacteristicsCapacitor SelectionMultilayer capacitors (MLC) and single layer capacitors are categorized by performance with temperature. Component selection is typically determined by dielectric performance, electrical environment, and temperature stability.

In determining the proper component for a specific application, the following information should be considered.

Dielectric TypeThere are three basic dielectric classes (characteristics) available: Dielectric Properties Dielectric Type Stability Class Description

BP Ultra Stable (NPO and COG) Class I Effects on electrical properties are minimal with temperature, frequency, or time. Used in applications which require stable performance.

BQ Stable BX and X7R Class II Effects on electrical properties predictably change with temperature, voltage, frequency and time. Selected for applications where blocking, coupling, by-passing, and frequency discriminating elements are used. Offers higher capacitance than Class I (COG).

Z5U and Y5V General Purpose Class II Exhibits a greater variation of properties with temperature. Dielectric constant is higher than Class I and Class II dielectrics. Extremely high capacitance per unit volume and used in general performance applications.

Dielectric Characteristics NPO (COG)Operating Temperature Range: -55°C to 125°C Temperature Coefficient: 0 ± 30 ppm/°C Dissipation Factor: .001 (0.1%) max.@25°C Insulation Resistance: 25°C 106 Megohms 125°C 105 Megohms Dielectric Withstanding Voltage: 50 to 200V, 2.5 x VDCW 201 to 500V, 1.5 x VDCW, or 500V* >500V, 1.2 VDCW or 750V* Aging Rate: 0% per decade hour. Test Parameters: 1 KHz, 1.0 ± 0.2 VRMS, 25°C 1 MHz for capacitance ≤1,000 pF

*Whichever is greater

Capacitor SizeThe capacitor body size impacts its utility to the design requirements in respect to capacitance value and voltage rating. Typically smaller units are less expensive and provide for greater space savings. Because mass affects the thermal response of the chips, size should be considered when selecting the attachment method to the circuit.

Termination MaterialMaterial Type Recommended Usage

Silver Palladium: Nonmagnetic application requirements. Recommended for conductive epoxy and leaded attachment methods. For soldering applications, use solder reflow below 230°C.

Silver: Most ductile of the available termination methods. Used in applications which will be leaded, to minimize thermal stresses.

General Soldering Recommendations for Leadless Ceramic CapacitorsSoldering Ceramic Capacitors with High Temperature Process SN10 Solder Ramp Rate, Heating and Cooling: Approx. 30°C/min. Peak Temperature: Approx. 320°C Dwell at Peak: <30 Seconds

Soldering Ceramic Capacitors with Medium Temperature Process SN96 Solder Ramp Rate, Heating and Cooling: Approx. 30°C/min. Peak Temperature: Approx. 250°C Dwell at Peak: <30 Seconds

Soldering Ceramic Capacitors with Low Temperature wProcess SN62 Solder Ramp Rate, Heating and Cooling: Approx. 30°C/min. Peak Temperature: Approx. 220°C Dwell at Peak: <30 Seconds

NotesCare must be taken to minimize the time silver terminations are exposed to molten solder to avoid leaching (amalgamation of the silver into molten solder). APITech recommends the use of a silver (Ag) bearing solder when terminating directly to ceramic ceramic capacitors to reduce the potential for leeching. Gradual heating and cooling of the components are essential to prevent thermal stresses to the ceramic.

Application Note: Soldering Recommendations for Switch Mode Power Supply Capacitors• SMPS capacitors are highly durable structures

designed to provide long service per lifetime, however they require attention to basic considerations during assembly. Like all ceramic components, SMPS capacitors are subject to thermal stresses. For this reason, preheating of the capacitor assemblies is recommended. Preheat components using hot plate to 120 to 150°C, or within 50 to 60°C of the soldering temperature being applied. Avoid over-exposure to high temperatures during assembly and allow for gradual, post-assembly cooling.

• For hand iron soldering, recommended soldering iron tip temperature is 330 to 350°C. Contact the pad adjacent to the pre-tinned lead should be made from below the PCB (opposite of the component side), and the dwell time on the solder joint should be less than five seconds. An aluminum heat sink plate may be placed adjacent to the SMPS lead frame to protect the ceramic body during assembly. Avoid direct contact between soldering iron and ceramic during assembly process. Soldering time is dependant upon heat sinking provided by the chasis and boardmaterial, so a longer preheat cycle may be required.

• Standard solders (Sn60, Sn63, Sn60/38/2) may be used. Please consult the factory for use with RoHS compliant solders.

• Use a controlled temperature profile ramp not exceeding 4°C per second as measured by an attached low mass thermocouple.

• Soldering time and temperatures can vary with component size, board material and layout. Please consult the factory for assistance.

High Voltage Ceramic Capacitors (HVCC) Part Numbering SystemThe part number shown represents a 2225 size high voltage capacitor. The ceramic type is X7R/BX, capacitance value is 0.82 µF, with a tolerance of ±10%. The voltage rating is 630 VDC, termination is “6” Ag termination, and the parts will be unmarked with bulk packaging.

Example: 2225X824KF6UB00

Soldering GuidelinesHVCCs are compatible with all soldering/mounting methods for chip capacitors.

Reflow SolderingAPITech recommends reflow soldering as the preferred method for mounting HVCCs. HVCCs can be reflow soldered using a reflow profile generally defined in IPC-FEDEC-J-STD-020. Silver termination chip capacitors are compatible with both conventional and lead-free soldering with a peak temperature of 260°C to 270°C acceptable.

The heating ramp rate should be such that components see a temperature rise of 1.5°C to 4°C

per second to maintain temperature uniformity through the HVCC.

The time for which the solder is molten, should be maintained at a minimum, so as to prevent solder leaching.

The use of an inert atmosphere can help if this problem is encountered. Palladium/Silver (Pd/Ag) terminations can be particularly susceptible to leaching with free lead, tin rich solders, and trials are recommended for this combination.

Cooling to ambient temperature should be allowed to occur naturally, particularly if larger chip sizes are being soldered.

DATA SHEET



Natural cooling allows a gradual relaxation of thermal mismatch stresses in the solder joints. Forced cooling should be avoided as this can induce thermal breakage.

Wave SolderingWave soldering is not acceptable.

Solder LeachingLeaching is the term for the dissolution of silver into the solder causing a failure of the termination system which causes increased ESR, tan δ and open circuit faults, including ultimately the possibility of the chip becoming detached.

Leaching occurs more readily with higher temperature solders and solders with a high tin content. Pb free solders can be very prone to leaching certain termination systems. To prevent leaching, exercise care when choosing solder allows and minimize both maximum temperature and dwell time with the molten solder.

Rework of Chip CapacitorsAPITech recommends hot air/gas as the preferred method of applying heat for rework. Apply even heat surrounding the component to minimize internal thermal gradients. Soldering irons or other techniques that apply direct heat to the chip or surrounding area should not be used as these can result in micro-cracks being generated.

Minimize the rework heat duration and allow components to cool naturally after soldering.

Use of Silver loaded Epoxy AdhesivesChip capacitors can be mounted to circuit boards using silver loaded adhesive, provided the termination material of the capacitor is selected to be compatible with the adhesive. This is normally PdAg.

HandlingHVCCs should never be handled with fingers. Skin oils and perspiration and can inhibit solderability and will aggravate cleaning.

Components should never be handled with metallic instruments. Metal tweezers should never be used as these can chip the product and leave abraded metal tracks on the product surface. Plastic or plastic-coated metal types are readily available and recommended – these should be used with an absolute minimum of applied pressure.

StorageIncorrect storage of HVCCs can lead to problems for the end-user. Rapid tarnishing of the terminations, with an associated degradation of solderability, will occur if the product comes into contact with industrial gases such as sulfur dioxide and chlorine.

Storage in moist or polluted air can result in termination oxidation.

Packaging should not be opened until the HVCCs are required for use. If opened, the pack should be re-sealed as soon as practicable. Alternatively, the contents could be kept in a sealed container with an environmental control agent.

For long term storage, conditions should, ideally, be temperature-controlled environments between -5°C and +40°C and between 40% and 60% relative humidity-controlled.

Taped products should be stored out of direct sunlight. This could promote deterioration in tape or adhesive performance.

HVCC products, stored under the conditions recommended above, in its “as received” packaging, has a minimum shelf life of 2 years.

Surface Mount Pad DesignAPITech’s conventional 2-terminal chip capacitors can generally be mounted using pad designs in for accordance with IPC-7351, Generic Requirements Surface Mount Design and Land Pattern Standards.



DATA SHEET



However, there are some other factors that have been shown to reduce mechanical stress, such as reducing the pad width to less than the chip width. The position of the chip on the board should also be considered.

Multilayer ceramic chip with nickel or copper barrier termination

REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) StatementThe main purpose of REACH is to improve the protection of human health and the environment from the risks arising from the use of chemicals.

RoHS ComplianceAPITech routinely monitors worldwide material restrictions (EU/China and Korea RoHS mandates) and is actively involved in shaping future legislation.

Breakdown of material content, SGS analysis reports are available upon request.

Most of APITech’s HVCC components are available with non-RoHS compliant tin/lead (Sn/Pb) solderable termination finish for exempt applications and where pure tin in not acceptable. Other tin-free termination finishes may also be available. Please contact us for additional details.

Ceramic Capacitors and AgingCapacitor aging is a term used to describe the negative, logarithmic capacitance change which takes place in ceramic capacitors with time. The crystalline structure for barium titanate based ceramics changes on passing through its Curie temperature (known as the Curie Point) at about 125ºC. The domain structure relaxes with time and in doing so. The dielectric constant reduces logarithmically; this is known as the aging mechanism of the dielectric constant. The more stable dielectrics have the lowest aging rates.

The aging process is reversible and repeatable. Whenever the capacitor is heated to a temperature above the Curie Point the aging process starts again from zero. The aging constant, or aging rate, is defined as the percentage loss of capacitance due to the aging process of the dielectric which occurs during a decade of time (a tenfold increase in age) and is expressed as a percent per logarithmic decade of hours. As the law of decrease of capacitance is logarithmic, this means that for a capacitor with an aging rate of 1% per decade of time, the capacitance will decrease at a rate of:

• 1% between 1 and 10 hours

• An additional 1% between the following 10 and 100 hours



• The aging rate continues in this manner throughout the life of the capacitor

Typical values of the aging constant for our HVCCs are:
