Procurement Notes

Verify the specific suffix JH-P against official KEMET documentation to confirm lead time and availability status. Confirm that the part is not obsolete before finalizing procurement plans. Ensure compatibility with existing thermal management solutions due to the high operating temperature rating. Cross-reference the manufacturer's latest datasheet for any recent design changes or end-of-life notifications.

Selection Notes

Select this component when three-phase common mode attenuation is required at 14 A continuous current. The 2.5 mH inductance value targets specific EMI frequency bands. Verify that the through-hole form factor fits the mechanical constraints of the target enclosure. Ensure the system voltage does not exceed the 500 V rating under all transient conditions.

Part Context

This part belongs to the KEMET SCR Three-Phase series, which specializes in common mode chokes for power applications. The series is characterized by high current handling capabilities and thermal stability. It serves as a critical passive component for meeting electromagnetic interference standards in heavy-duty electrical equipment.

Replacement Considerations

Public sources indicate aliases such as UALBA1R8A025JH. Verify functional equivalence with other KEMET SCR series parts if supply chain constraints exist. Ensure replacement components match the 2.5 mH inductance and 14 A current rating.
