Procurement Notes
Verify the specific part number SSR21NVS-M07680 against official KEMET documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with PCB mounting requirements and thermal management needs. Cross-reference datasheets for any recent product change notices or obsolescence alerts before finalizing procurement decisions.
Selection Notes
Select this component when a 68mH inductance and 0.7A current rating are required for common mode noise attenuation. Consider the through-hole package style and 250VAC voltage rating for suitability in mains-powered circuits. Evaluate the 950 mOhm DC resistance impact on circuit efficiency and ensure the operating temperature range meets environmental specifications.
Part Context
This component belongs to the KEMET SSR21NVS series of common mode chokes. These components are engineered for AC line filtering and feature through-hole termination for robust PCB integration. The series utilizes ferrite cores to provide effective noise suppression while maintaining low DC resistance characteristics suitable for power line applications.
Replacement Considerations
Publicly confirmed substitute part numbers for this specific model were not identified in available documentation. Verify compatibility with alternative components by matching inductance, current rating, voltage rating, and physical footprint dimensions.
