Overview
The SH-121 is a through-hole common mode choke from the KEMET SH series, designed for DC line filtering. It features an inductance of 0.35 µH at 100 kHz and supports a maximum DC current of 3 A. The component has a low DC resistance of 11 mΩ and a rated voltage of 50 V DC. It operates within a temperature range of -25 °C to 80 °C and utilizes a nickel-zinc core material.
Feature Summary
- Provides common mode noise suppression for DC power lines
- Utilizes a nickel-zinc core for effective high-frequency attenuation
- Designed for robust through-hole PCB mounting
Applications
- DC power line filtering
- EMI suppression in electronic circuits
- Common mode noise reduction in industrial equipment
Procurement Notes
Verify end-of-life status as the SH-121 is listed as obsolete with a PCN dated November 28, 2025. Confirm RoHS compliance (RoHS3) and check for available replacement components from the same manufacturer family before procurement planning.
Selection Notes
Select this component for applications requiring 0.35 µH inductance and 3 A current handling in a through-hole format. Ensure the operating environment stays within the -25 °C to 80 °C range and that the 50 V DC rating meets circuit requirements.
Part Context
The SH-121 belongs to the SH series of DC line filters manufactured by KEMET. This series focuses on common mode chokes for suppressing electromagnetic interference in direct current applications, offering a compact solution for noise mitigation in power supply lines.
Replacement Considerations
The part is marked as End of Life. Verify if other SH series variants or equivalent common mode chokes from KEMET are available as direct replacements.
