SS21VB-R220010

Overview

The KEMET SS21VB-R220010 is a radial leaded common mode choke designed for AC line filtering applications. It features a ferrite core and provides an inductance of 1 mH with a rated current of 2.2 A. The component exhibits a DC resistance of 5.90 Ω and supports voltage ratings of 250 V ac and 500 V ac. These specifications enable effective noise suppression in power supply circuits while maintaining low insertion loss.

Feature Summary

• Radial leaded construction facilitates through-hole mounting on printed circuit boards
• Ferrite core material ensures stable magnetic performance under varying load conditions
• Common mode topology suppresses electromagnetic interference on AC lines

Applications

• Digital appliances power input stages
• Industrial equipment EMI mitigation
• AC line filtering in consumer electronics

Procurement Notes

Verify the specific inductance value and current rating against the official datasheet to ensure compatibility with the target circuit requirements. Confirm that the radial lead configuration matches the PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when a radial form factor is required for AC line filtering in digital or industrial applications. Ensure the 2.2 A current rating meets the maximum operational load. Verify that the 5.90 Ω DC resistance does not cause excessive voltage drop in the power path compared to alternative surface mount options.

Part Context

This component belongs to the 21VB series of common mode chokes manufactured by KEMET. The series focuses on providing reliable electromagnetic interference suppression for AC power lines using ferrite core technology. The radial lead design distinguishes it from surface mount alternatives, catering to traditional through-hole manufacturing processes.
