TRADITIONALPb
*Add “LF” suffix for RoHS requirement. Example: CMF3-2502SMLFGowanda designates a component RoHS-compliant by adding “LF” (lead free) to the part number. These LF components meet the ≤ .1% lead requirement and they are compatible with 260°C soldering processes.

NOTES:
• Operating Temperature Range: -55°C to +125°C
• Current Rating is based on a 50°C temperature rise at an ambient temperature of 75°C Note: Current is rated in both windings
• Dielectric Withstanding Voltage (DWV) is 1250 Vrms
• Excellent electromagnetic shielding• Leakage inductance is tested at pins 1-2 with
pins 3-4 shorted or at pins 3-4 with pins 1-2 shorted
• Inductance and DCR is for each side or single winding
• Windings balanced within 2%• Applications include reduction of AC line
interference produced by switching power supplies (the opposing magnetic fluxes in the core serve to cancel in-phase noise signals appearing across the AC line) and noise suppression of DC circuits for switching regulators
