A. PASSIVEELECTRONIC

COMPONENT

1. Capacitors is a passive two-terminalelectrical

component used

to store energyelectrostatically

in an electric

field.

They are used for

filtering power supplylines, tuning resonant

circuits, and for

blocking DC voltageswhile passing AC

signals, among

numerous other uses.

1.1 Tuning

capacitor

used in L/C circuits to

set the resonance

frequency, e.g. to tune

a radio

1.2 Trimmercapacitor

small variablecapacitor usually

for internal

adjustments

often used to initiallycalibrate equipment

after manufacturing.

1.3 Vacuum

used in equipment such

as highpowered broadcast tran

smitters,Amateur

be applied to heating

elements in irons,

toasters, heaters,electric stoves and hair

dryers, which dissipate

voltage as heat

of analog signals (for

example volume

controls on audioequipment), and as

control inputs forelectronic circuits. For

brightness of lamps.

2.2 Rheostat two-terminal

variable resistor(often for high

power)

rheostat is used to

adjust generatorcharacteristics, dim

lights, and start orcontrol the speed ofmotors.

2.3 Trimpot Smallpotentiometer,

usually for

internaladjustments

fine-tuning and otheradjustments.

2.4 Thermistor temperature-varied resistor

PTC thermistors can beused as current-

limiting devices for

circuit protection, asreplacements for fuses.PTC thermistors were

used as timers in the

degaussing coil circuitof most CRT displays.

Thermistors are often

used in the hot ends of3D printers; they

monitor the heat

produced and allow the

printer's controlcircuitry to keep a

constant temperature

for melting the plasticfilament.
