Common Mode Chokes Selection Notes

Select this component when designing circuits requiring common mode noise suppression for high-speed digital interfaces. Ensure the operating current remains below the 370 mA rating to prevent saturation. Verify that the physical footprint matches the PCB land pattern and that the impedance characteristics meet the EMI requirements of the target application environment.

Common Mode Chokes Part Context

This part belongs to the CCMC series of common mode chokes from Pulse Electronics. These components are engineered for compact electronic designs where space constraints limit the use of larger through-hole filters. The series provides reliable noise attenuation for sensitive data lines in consumer and industrial electronics.

Common Mode Chokes Replacement Considerations

Consult official substitution guides for equivalent parts with matching impedance and current ratings. Verify pin compatibility and thermal characteristics before integrating alternative components into existing designs.
