Common Mode Chokes Procurement Notes

Verify the complete part number DKFP-B22B-1K6Q against manufacturer datasheets to confirm specific electrical tolerances and mechanical dimensions. Ensure compatibility with existing PCB footprint requirements, specifically the 18.5 x 18 mm base area and 13 mm height clearance. Confirm that the 1.2 A current rating and 6.8 mH inductance meet the target circuit design specifications before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when a compact, current-compensated choke is required for noise suppression in low-current applications up to 1.2 A. The 6.8 mH inductance and 600 kHz self-resonant frequency make it suitable for specific EMI filtering needs. Consider the through-hole mounting style and operating temperature range of -40 °C to +125 °C for environmental suitability.

Common Mode Chokes Part Context

This component belongs to the DKFP series of current compensated chokes manufactured by Schurter Inc. These devices are engineered as compact magnetic components for noise suppression. The DKFP series offers various inductance and current ratings to accommodate different circuit requirements while maintaining a consistent small footprint and through-hole installation method.

Common Mode Chokes Replacement Considerations

Cross-reference with other DKFP series variants such as DKFP-B22B-D810 or DKFP-B22B-04D7 if different inductance or current ratings are needed. Verify pinout and dimensional compatibility before substituting with similar components from other manufacturers.
