Common Mode Chokes Procurement Notes

Verify the specific part number DKFP-A21A-0103 against official Schurter documentation to ensure correct specifications. Confirm that the 1A current rating and 200mOhm DCR meet your circuit requirements. Check for any specific ordering suffixes that may indicate different tolerances or packaging options. Ensure compatibility with your PCB layout regarding the through-hole footprint and lead diameter.

Common Mode Chokes Selection Notes

Select this component when common mode noise suppression is required for two-line circuits operating at 250VAC. Consider the 1A current rating and 200mOhm DC resistance for power loss calculations. Verify that the through-hole mounting style fits your assembly process. Ensure the operating temperature range covers your application's environmental conditions.

Common Mode Chokes Part Context

This component belongs to the DKFP series of magnetically compensated chokes from Schurter. These components are designed for compact noise suppression in industrial settings. The series offers various current ratings and inductance values to suit different filtering needs while maintaining high reliability standards.

Common Mode Chokes Replacement Considerations

Check Schurter datasheets for alternative DKFP models with similar current ratings and voltage specifications. Ensure any substitute maintains the same through-hole package dimensions and lead spacing for direct replacement.
