Procurement Notes

Verify the specific suffix against official KEMET documentation to confirm electrical ratings and physical dimensions. Check for End-of-Life status or discontinuation notices prior to procurement. Ensure compatibility with existing PCB footprints and thermal management requirements during integration.

Selection Notes

Select this component when a 29 mH inductance and 700 mA current rating are required for common mode noise attenuation. Consider the 530 milliohm DCR for power loss calculations. Verify that the through-hole package fits the target assembly constraints and that the operating temperature range meets environmental specifications.

Part Context

This part belongs to the KEMET SSR21NVS series of AC line filters. These components are engineered for common mode interference reduction in single-phase AC circuits. The series offers various inductance and current combinations to suit different power line filtering needs while maintaining compact form factors for standard PCB layouts.

Replacement Considerations

SSR21NHS-07290 is a documented alternative within the same family. Verify pinout compatibility and exact parameter alignment before substitution.
