Common Mode Chokes Procurement Notes

Verify the specific suffix JKH against official Kemet documentation to confirm exact tolerance and packaging specifications. Ensure the procurement channel provides valid traceability for the UL 94 V-0 rating. Cross-reference the 12 mH inductance value with the manufacturer's datasheet to distinguish this variant from other SC-series models with different current ratings or impedance characteristics.

Common Mode Chokes Selection Notes

Select this component when circuit requirements demand 12 mH of common mode inductance with a continuous current handling capacity of 4 A. The 75 milliohm DC resistance indicates low insertion loss for power lines. Verify that the operating environment remains within the specified -25°C to +120°C thermal range and that the physical dimensions accommodate the PCB layout constraints for through-hole mounting.

Common Mode Chokes Part Context

This component belongs to the KEMET SC series of common mode chokes, which are characterized by their use of specialized ferrite materials for broadband noise suppression. The series offers various inductance values and current ratings tailored for different power levels. The SC-04-E120JKH specifically addresses applications requiring robust performance in the higher frequency spectrum while maintaining structural integrity under significant electrical load.

Common Mode Chokes Replacement Considerations

Direct substitutes must match the 12 mH inductance, 4 A current rating, and 75 milliohm resistance. Verify compatibility of the through-hole package dimensions and lead configuration. Ensure any alternative component meets the same UL 94 V-0 safety standard and operates effectively within the 150 kHz frequency range.
