All part numbers provide 30% tolerance on inductance
Custom designs are available to meet your specific requirements; please contact factory
*Add “LF” suffix for RoHS requirement. Example: CMF4-1003HLF
Gowanda 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
• Applications include reduction of AC line
interference 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
