SC-20-20JH

Overview

The KEMET SC-20-20JH is a two-line common mode filter designed for through-hole mounting. It features an inductance of 2.003 mH at 100 kHz and supports a rated current of 20 A. The component operates with a rated voltage of 250 V and provides dielectric strength up to 2.4 kV. Its low DC resistance is specified at 10 mΩ, ensuring minimal signal loss while effectively suppressing electromagnetic interference in power line applications.

Feature Summary

• Provides effective common mode noise suppression for multi-phase power lines
• Engineered for high current handling capabilities in industrial environments
• Features robust insulation suitable for mains voltage isolation requirements

Applications

• Switch mode power supplies (SMPS)
• Industrial drives and motor controllers
• Welding equipment
• Uninterruptible power supplies (UPS)

Procurement Notes

Verify the specific suffix JH against official KEMET documentation to confirm lead frame material and plating specifications. Ensure the selected variant matches the required thermal rating and mechanical footprint for the target PCB layout. Cross-reference the datasheet version to validate compliance with current RoHS directives and safety certifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring high current capacity alongside significant common mode attenuation. Evaluate the 20 A rating against peak load conditions to prevent saturation. Consider the 2.4 kV withstand voltage for systems demanding enhanced isolation between primary and secondary sides or phases.

Part Context

This part belongs to KEMET's SC series of common mode chokes, which are engineered for power line filtering. The series utilizes toroidal cores to achieve high permeability and inductance density. These components are integral to maintaining electromagnetic compatibility in sensitive electronic equipment exposed to noisy power environments.

Replacement Considerations

Consult official KEMET substitution guides for verified alternatives. Generic equivalents may not match the specific 2.003 mH tolerance or 20 A thermal limits.
