SSR21NHS-M041350

Overview

The KEMET SSR21NHS-M041350 is a single-channel common mode choke designed for PCB mounting via through-hole termination. It features an inductance of 135 mH measured at 10 kHz 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 -40°C to +120°C. Constructed with proprietary S15H ferrite material, it offers high permeability and impedance across a wide frequency range.

Feature Summary

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

Applications

• AC line filtering applications
• Common mode noise suppression in electronic circuits
• PCB-mounted power supply input stages

Procurement Notes

Verify the specific suffix M041350 against official KEMET documentation to confirm the 135 mH inductance and 400 mA current rating. Ensure the procurement channel provides valid RoHS compliance data and confirms the operating temperature range matches the specified -40°C to +120°C limits before integration.

Selection Notes

Select this component when high inductance is required for low-current AC line filtering. The through-hole package suits manual or wave soldering processes. Consider the 2 Ohm DC resistance impact on voltage drop if the load current approaches the 400 mA maximum rating during initial circuit design.

Part Context

This part belongs to the SSR21NHS-M series of common mode chokes from KEMET. These components are categorized under AC Line Filters and Inductors, Chokes & Coils. The series utilizes ferrite cores optimized for common mode noise reduction in compact PCB footprints.
