SSR21NHS-031590

Overview

The KEMET SSR21NHS-031590 is a through-hole common mode choke designed for AC line filtering applications. It operates at a rated voltage of 250VAC and supports a maximum DC current of 300mA. The component provides an inductance of 159mH, measured at a test frequency of 10kHz, with a maximum DC resistance of 2.85 Ohms. It functions within a temperature range of -25°C to +120°C. The device utilizes proprietary S15H ferrite material and features a divided bobbin structure to achieve high impedance across a wide frequency range.

Feature Summary

Utilizes proprietary S15H ferrite material for high permeability
Employs a divided bobbin design to maintain high impedance over a wide frequency range
Features a compact, low-profile, and lightweight construction

Applications

AC line filtering
Common mode noise suppression
Electronic equipment power input stages

Procurement Notes

Verify the specific part number against official KEMET documentation to ensure compatibility with your circuit requirements. Confirm that the 300mA current rating and 159mH inductance meet your design 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 through-hole common mode choke with 159mH inductance and 300mA current handling is required. The S15H ferrite core offers high permeability suitable for broad frequency noise attenuation. Ensure the PCB layout accommodates the physical dimensions and through-hole termination style specified for this series.

Part Context

This component belongs to the SSR21NHS series of common mode chokes manufactured by KEMET. The series is characterized by the use of S15H ferrite material and divided bobbin technology.
