SC-20-03J

Overview

The KEMET SC-20-03J is a through-hole common mode choke from the SC-J series. It features an inductance of 300 µH and supports a maximum DC current of 20 A. The component has a maximum DC resistance of 4 mΩ and operates within a temperature range of -25°C to +120°C.

Feature Summary

• Provides common mode noise suppression for power lines
• Designed for through-hole mounting with leads suitable for wave or hand soldering

Applications

• Power supply input filtering
• EMI suppression in AC/DC converters
• Noise reduction in industrial equipment power stages

Procurement Notes

Verify the specific datasheet version for the SC-20-03J to confirm lead form and RoHS compliance status. Ensure the selected variant matches the required 20A current rating and 300µH inductance specifications for your circuit design.

Selection Notes

Select this component when high current handling capability up to 20A is required alongside common mode filtering. The low DC resistance minimizes power loss, while the wide operating temperature range ensures reliability in demanding environments.

Part Context

This part belongs to the KEMET SC-J series of common mode chokes. These components are engineered for power line applications where significant current capacity and effective electromagnetic interference attenuation are necessary.

Replacement Considerations

Check for direct substitutes within the SC-J series or equivalent parts from other manufacturers offering 300µH inductance and 20A current ratings with compatible through-hole packaging.
