SC-18-15JH

Overview

The KEMET SC-18-15JH is a single-channel common mode choke designed for PCB mounting via through-hole termination. It provides an inductance of 1.5 mH with a maximum DC current rating of 18 A and a maximum DC resistance of 10 mOhms. The component operates within a temperature range of -25°C to +105°C and is rated for 250V.

Feature Summary

• Provides effective common mode noise suppression for AC line applications
• Features high permeability nanocrystalline metal core construction
• Supports high current handling capabilities suitable for power filtering

Applications

• AC line filtering in electronic equipment
• Power supply input stages
• EMI suppression circuits

Procurement Notes

Verify the specific datasheet version to confirm the exact DC resistance value, as sources indicate variations between 7 mOhms and 10 mOhms. Ensure the through-hole footprint dimensions match the target PCB layout. Confirm RoHS compliance status directly from the manufacturer's documentation before finalizing procurement.

Selection Notes

Select this component when a 1.5 mH inductance at 18 A is required for common mode noise reduction. Compare against the SC-12-15JH if lower current capacity is acceptable. Verify that the operating temperature range meets the environmental requirements of the specific application design.

Part Context

This part belongs to the KEMET SC-J series of common mode chokes. These components utilize toroidal coils with nanocrystalline metal cores to achieve ultra-high inductance and permeability. The series is designed for robust performance in demanding power filtering environments.

Replacement Considerations

The SC-12-15JH is a related model within the same series but supports a lower maximum DC current of 12 A. Verify that the reduced current rating does not compromise the safety margins of the target circuit design.
