Procurement Notes

Verify the specific suffix J against the manufacturer datasheet to confirm tolerance and material specifications. Ensure the ordering part number matches the required inductance and current ratings for the target circuit design. Cross-reference the alias UAL20R55A250J if sourcing from distributors using alternate nomenclature.

Selection Notes

Select this component when a 25 mH common mode choke with a 2 A current rating is required for through-hole implementation. Consider the physical footprint of 29x27x23 mm for board layout constraints. Verify that the 200 mOhm DCR meets the voltage drop requirements of the application.

Part Context

This component belongs to the KEMET SCR series of common mode chokes. The series offers various inductance values and current ratings for EMI filtering. The SCR-020 variant specifically denotes the case size and performance class within the broader product family.

Replacement Considerations

The part is also identified by the alias UAL20R55A250J. Verify compatibility with other 25 mH, 2 A common mode chokes from different manufacturers based on pinout and mechanical dimensions.
