SSR21NVS-M051200

Overview

The KEMET SSR21NVS-M051200 is a through-hole common mode choke designed for AC line filtering applications. It features an inductance of 120 mH at a test frequency of 10 kHz and supports a maximum DC current of 500 mA. The component has a maximum DC resistance of 1.85 Ohms and is rated for 250 VAC. It operates within a temperature range of -40°C to +120°C. The physical dimensions are 3.5 mm in length, 27 mm in height, and 22 mm in diameter.

Feature Summary

• Utilizes proprietary S15H ferrite material for high permeability
• Provides high impedance across a wide frequency range due to divided bobbin construction
• Achieves higher performance through additional windings

Applications

• AC line filtering
• Common mode noise suppression

Procurement Notes

Verify the specific part number against official KEMET documentation to ensure compatibility with design requirements. Confirm that the 120 mH inductance and 500 mA current rating align with circuit specifications. Check for any recent product change notices or end-of-life announcements from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 120 mH common mode choke is required for through-hole PCB mounting. Ensure the application environment stays within the -40°C to +120°C operating temperature range. Verify that the 500 mA current capacity meets the load requirements and that the 1.85 Ohm DC resistance is acceptable for the circuit design.
