Procurement Notes
Verify the manufacturer part number SS21V-300008 against official KEMET documentation to confirm specifications. Ensure compatibility with required voltage, current, and inductance parameters. Check for RoHS compliance status as indicated in the datasheet. Confirm package type and mounting style match design requirements before procurement.
Selection Notes
Select this component when a 0.8 mH inductance and 3 A current rating are required for common mode filtering. Consider the 250 VAC rating and through-hole package for PCB layout constraints. Evaluate thermal performance within the specified operating temperature range. Compare electrical characteristics against alternative filters in the SS21V series if different ratings are needed.
Part Context
This component belongs to the KEMET SS21V series of common mode chokes. These filters are engineered for general-purpose AC line filtering applications. The series offers various inductance and current ratings to suit different power supply designs. The SS21V-300008 specifically targets applications requiring moderate inductance and high current handling capabilities.
Replacement Considerations
Check KEMET's SS21V series for alternatives with different inductance or current ratings. Verify pinout and physical dimensions for direct replacement. Consult official substitution guides for cross-references.
