Common Mode Chokes Procurement Notes

Verify the complete part number including suffixes against official Schurter documentation to ensure correct inductance and current ratings. Confirm that the through-hole package style matches your PCB layout requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the chassis or panel mount configuration aligns with your enclosure design constraints before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when high current handling capability combined with significant common mode noise attenuation is required. The 25 mH inductance offers strong filtering characteristics for lower frequency interference. Verify that the 1.7 mOhm DC resistance meets your efficiency targets. Consider the physical dimensions and mounting style to ensure compatibility with your assembly process and spatial constraints.

Common Mode Chokes Part Context

This component belongs to the DKIV series of current compensated chokes from Schurter. These devices are specifically engineered for power line applications where high current capacity and effective noise suppression are critical. The series utilizes advanced magnetic materials to achieve high inductance values without saturating at high DC currents, making them suitable for modern switching power supplies.

Common Mode Chokes Replacement Considerations

Consult Schurter's official cross-reference guides for verified substitutes. Ensure any replacement maintains the 25 mH inductance, 40 A current rating, and 1.7 mOhm resistance specifications. Verify mechanical compatibility including lead spacing and mounting hole configurations.
