Common Mode Chokes Procurement Notes

Verify the specific part number DKFP-D22D-034K against official Schurter documentation to ensure accuracy. Confirm that the required inductance, current rating, and physical footprint match the design specifications. Check for any specific ordering suffixes or packaging variations if applicable. Ensure compliance with relevant safety standards for the intended application environment.

Common Mode Chokes Selection Notes

Select this component when a compact, magnetically compensated choke is required for high-current applications up to 3 A. The 4.2 mH inductance and 63 mohm resistance balance performance with size constraints. Consider the through-hole requirement and operating temperature range of -40°C to +125°C during circuit design integration.

Common Mode Chokes Part Context

This component belongs to the DKFP series of current compensated chokes from Schurter. These components are designed for noise suppression in electronic circuits. The DKFP series offers various inductance and current ratings to suit different power levels and space requirements while maintaining low DC resistance.

Common Mode Chokes Replacement Considerations

Consult Schurter's official cross-reference data for verified substitutes. Ensure replacement parts match the 4.2 mH inductance, 3 A current rating, and 29x28x17 mm dimensions. Verify pinout compatibility and thermal characteristics before substitution.
