SSR21NH-M041500

Overview

The KEMET SSR21NH-M041500 is a through-hole common mode choke designed for AC line filtering applications. It features an inductance of 150 mH and supports a maximum DC current of 400 mA. The component has a maximum DC resistance of 2 Ohms and operates within a temperature range of -25°C to +120°C. Rated for 250 VAC, it utilizes a bobbin construction with dimensions of 3.5 mm length, 23 mm width, and 14.5 mm height.

Feature Summary

• Provides common mode noise suppression for AC power lines
• Utilizes through-hole mounting for PCB integration
• Constructed with a bobbin design for structural stability

Applications

• AC line input filtering
• Power supply EMI reduction
• Electronic equipment noise suppression

Procurement Notes

Verify the specific suffix (NH) against the official KEMET datasheet to confirm electrical characteristics and physical dimensions. Ensure the ordering part number matches the required inductance and current ratings for the target circuit design before procurement.

Selection Notes

Select this component when high inductance is required for low-current AC line filtering. The 400 mA rating limits suitability for higher power applications. Verify that the through-hole footprint and height constraints fit the mechanical design requirements of the assembly.

Part Context

This part belongs to the SSR21NV-M/NH-M series of through-hole bobbin common mode chokes from KEMET. These components are categorized as AC line filters intended for electromagnetic interference suppression in electronic circuits requiring robust common mode noise attenuation.

Replacement Considerations

Check for direct substitutes within the same series or comparable common mode chokes with matching 150 mH inductance and 400 mA current ratings. Ensure pin compatibility and thermal performance align with the original design specifications.
