Common Mode Chokes Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with KEMET or authorized distributors before procurement. Confirm that the 50 mOhm DCR specification aligns with your thermal management requirements. Ensure the through-hole footprint dimensions match your PCB layout constraints. Cross-reference the part number against official KEMET catalogs to avoid counterfeit components.

Common Mode Chokes Selection Notes

Select this component when high current handling up to 8 A is required alongside significant common mode noise attenuation. The wide operating temperature range suits industrial environments. Compare its physical dimensions against available board space. Consider the toroidal geometry for compactness compared to other choke types offering similar performance metrics.

Common Mode Chokes Part Context

This part belongs to the KEMET SC-J series of through-hole common mode chokes. The series utilizes toroidal coils with nanocrystalline metal cores to achieve superior magnetic properties. These components are engineered for demanding power applications where size and efficiency are critical factors in system design.

Common Mode Chokes Replacement Considerations

Check KEMET's official substitution guide for equivalent parts within the SC series. Verify that any alternative maintains the 2 mH inductance and 8 A current rating. Ensure the replacement fits the same through-hole package and meets the 250 VAC voltage requirement.
