Procurement Notes
Verify the specific part number against official KEMET documentation to ensure compatibility with design requirements. Confirm that the 500 mA current rating and 79.5 mH inductance meet the circuit specifications. Check for any recent product discontinuation notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when a common mode choke with 79.5 mH inductance and 500 mA current capacity is required for through-hole assembly. Ensure the PCB layout accommodates the 16 mm width and 27 mm height dimensions. Verify that the 1.2 Ohm DC resistance aligns with the system's voltage drop constraints and thermal management capabilities.
Part Context
This component belongs to the KEMET SSR21NV series of AC line filters. These chokes are engineered for common mode interference suppression in single-phase AC applications. The series offers various inductance and current ratings to suit different power line filtering needs while maintaining standard through-hole package dimensions for widespread compatibility.
Replacement Considerations
Publicly confirmed substitute part numbers for this specific component were not identified in the provided source material. Consult official KEMET resources for potential cross-references or updated equivalents if availability is a concern.
