SN12-400

Overview

The KEMET SN12-400 is a through-hole differential mode choke designed for power line filtering. It features an inductance of 64 µH and supports a maximum DC current of 5 A. The component has a maximum DC resistance of 32 mΩ and operates within a temperature range starting from -25°C. It utilizes wire terminals for mounting.

Feature Summary

• Provides differential mode noise suppression for power lines
• Supports high current handling up to 5 A
• Utilizes through-hole wire terminal construction

Applications

• Power line filtering
• Differential mode chokes
• EMI suppression circuits

Procurement Notes

Verify the specific suffix against official KEMET documentation to ensure exact electrical matching, as variations may exist within the SN-J series. Confirm that the 5 A current rating and 32 mΩ resistance align with your circuit requirements before procurement.

Selection Notes

Select this component when differential mode attenuation is required at 64 µH with a 5 A current capacity. Ensure the PCB layout accommodates through-hole wire terminals and that the operating environment exceeds the -25°C minimum threshold.

Part Context

This part belongs to the KEMET SN-J series of through-hole differential mode chokes. These components are engineered for general power line applications where compact size and reliable noise suppression are necessary. The series offers standardized inductance values for common EMI filtering needs.

Replacement Considerations

Check for other SN-J series variants with identical 64 µH inductance and 5 A ratings. Verify physical dimensions and terminal compatibility before substituting.
