SSRH24NVS-20215

Overview

The KEMET SSRH24NVS-20215 is a through-hole common mode choke from the SSRH series. It features an inductance of 21.5 mH and a maximum DC current rating of 2 A. The component has a maximum DC resistance of 0.177 Ω and is rated for 250 V AC. It operates within a temperature range of -25 °C to 120 °C. The unit utilizes pad termination and measures 25.5 mm in length, 20 mm in depth, and 31 mm in height.

Feature Summary

• Provides common mode noise suppression for power lines
• Designed for through-hole mounting with pad termination
• Constructed for high thermal stability up to 120 °C

Applications

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

Procurement Notes

Verify the complete part number including suffixes against official KEMET documentation to ensure correct specifications. Confirm that the required operating temperature range and current ratings align with the design constraints. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the through-hole package dimensions fit the target PCB layout.

Selection Notes

Select this component when a 21.5 mH inductance at 2 A is required for common mode noise attenuation. The 0.177 Ω DC resistance indicates low insertion loss for the primary circuit. The 250 V AC rating suits standard mains voltage applications. Consider the physical dimensions of 25.5 x 20 x 31 mm for board space allocation during the initial design phase.

Part Context

This component belongs to the KEMET SSRH series of common mode chokes. These devices are engineered for power line filtering applications where significant inductance is needed at moderate current levels. The series typically offers robust performance for general industrial and consumer electronics environments requiring EMI mitigation on AC inputs.

Replacement Considerations

Cross-reference with other KEMET SSRH variants or equivalent common mode chokes from manufacturers like TDK or Murata. Ensure substitute parts match the 21.5 mH inductance, 2 A current rating, and 0.177 Ω DCR. Verify that the replacement maintains the same through-hole footprint and terminal configuration.
