SSR21NH-07405

Overview

The KEMET SSR21NH-07405 is a single-channel common mode choke designed for AC line filtering applications. It features an inductance of 40.5 mH measured at 10 kHz and supports a maximum DC current of 0.7 A. The component has a typical DC resistance (DCR) of 610 mOhms and is rated for 250 VAC. It utilizes through-hole mounting with dimensions of approximately 23 mm length, 23 mm width, and 14.5 mm height. The operating temperature range spans from -25°C to +120°C.

Feature Summary

• Provides common mode noise suppression for AC power lines
• Supports high-temperature operation up to 120°C
• Designed for through-hole PCB integration

Applications

• AC power line filtering
• EMI suppression in electronic equipment
• Common mode interference reduction in power supplies

Procurement Notes

Verify the specific suffix (NH vs NV) against official KEMET documentation to confirm mechanical and electrical specifications match project requirements. Ensure compatibility with through-hole assembly processes and verify that the 0.7 A current rating meets the circuit's operational demands without saturation.

Selection Notes

Select this component when common mode noise attenuation is required on AC lines with currents up to 0.7 A. The 40.5 mH inductance provides significant impedance at 10 kHz. Consider the physical dimensions and through-hole mounting style for PCB layout constraints. The wide temperature range suits environments with thermal variations.

Part Context

This part belongs to the KEMET SSR21NV/NH series of AC line filters. These components are engineered for common mode applications, offering standardized performance for EMI mitigation. The series includes variants with similar electrical characteristics but potentially different mechanical or packaging attributes, necessitating precise model identification.

Replacement Considerations

The SSR21NV-07405 shares identical electrical specifications (40.5 mH, 0.7 A, 610 mOhm DCR). Verify if mechanical differences between NH and NV suffixes impact board space or mounting requirements before substitution.
