SSR21NH-13140

Overview

The KEMET SSR21NH-13140 is a through-hole common mode choke designed for AC line filtering applications. It features an inductance of 14 mH measured at a test frequency of 10 kHz and supports a maximum DC current of 1.3 A. The component exhibits a maximum DC resistance of 210 mOhms and is rated for 250 VAC operation. It operates within a temperature range of -25 °C to +120 °C. The device utilizes ferrite core material and is supplied in tray packaging.

Feature Summary

• Provides common mode noise suppression for AC power lines
• Utilizes ferrite core construction for effective high-frequency attenuation
• Designed for through-hole PCB mounting

Applications

• AC line input filtering

• General electronic equipment noise reduction

Procurement Notes

Verify the specific part number against official KEMET documentation to ensure compatibility with design requirements. Confirm that the through-hole package dimensions and pin configuration match the target PCB layout. Check for RoHS compliance status if required by regulatory standards. Ensure the operating temperature range meets the environmental conditions of the final application.

Selection Notes

Select this component when a 14 mH inductance is required for common mode noise filtering at 1.3 A current levels. The low DC resistance minimizes power loss in the circuit. The wide operating temperature range allows for use in various thermal environments. Verify that the through-hole mounting style is suitable for the assembly process.

Part Context

This component belongs to the KEMET SSR21NV/NH series of AC line filters. These chokes are engineered for general-purpose EMI suppression in single-phase AC circuits. The series offers standardized inductance values and current ratings to simplify design integration for common mode interference mitigation.
