Procurement Notes
Verify the specific suffix against official KEMET documentation to confirm exact electrical tolerances and mechanical dimensions. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the datasheet revision date to ensure compliance with current RoHS standards and material declarations before finalizing orders.
Selection Notes
Select this component when designing circuits requiring 47.5 mH of common mode inductance at 1 A continuous current. Verify that the PCB footprint accommodates the specific lead spacing and body height constraints. Confirm that the operating environment remains within the specified -25°C to +120°C thermal limits to maintain performance stability and reliability over the product lifecycle.
Part Context
This part belongs to the SSR21NV-M series of common mode chokes manufactured by KEMET. The series offers various inductance and current ratings tailored for AC line filtering. The specific model distinguishes itself through its 47.5 mH inductance value and 1 A current handling capability, fitting into the broader portfolio of EMI suppression components for power electronics.
Replacement Considerations
Consult official KEMET substitution guides for verified alternatives. Do not assume functional equivalence with generic inductors without verifying inductance tolerance, saturation current, and physical footprint compatibility against the original datasheet specifications.
