SH-321

Overview

The KEMET SH-321 is a through-hole common mode choke filter designed for DC line applications. It features an inductance of 3.5 µH at 100 kHz and supports a maximum current of 3 A with a direct current resistance (DCR) of 14 mΩ. The component operates within a voltage rating of 50 V. Its physical dimensions are limited to a maximum length, width, and height of 12.5 mm, 10 mm, and 10 mm respectively, with a lead length of 4 mm ± tolerance.

Feature Summary

Provides common mode noise suppression for DC lines
Supports high current loads up to 3 A
Low direct current resistance for minimal power loss
Through-hole mounting for secure PCB integration

Applications

DC line filtering in electronic circuits
Noise suppression in low-voltage power supplies
Signal integrity protection in data lines

Procurement Notes

Verify the specific datasheet version for the SH-321 to confirm exact electrical tolerances and thermal characteristics. Ensure compatibility with existing PCB footprint dimensions, particularly the 4 mm lead length specification. Cross-reference manufacturer documentation for any updates regarding material compliance or pinout configurations before finalizing procurement.

Selection Notes

Select this component when low-profile common mode filtering is required for DC applications. The 3.5 µH inductance offers effective noise attenuation without significant impedance to signal transmission. Consider the 14 mΩ DCR for efficiency calculations in power-sensitive designs. The compact 10 mm height suits space-constrained enclosures.

Part Context

The SH-321 belongs to KEMET's range of passive electromagnetic components. It complements other EMI filters by providing targeted common mode rejection. As a through-hole device, it integrates into standard manufacturing processes. It serves as a reliable solution for mitigating electromagnetic interference in sensitive DC circuits.
