Common Mode Chokes Procurement Notes

Verify the exact part number DKIH-3242-257K-NK against manufacturer datasheets before procurement. Confirm that the 2.35 mH inductance and 25 A current ratings align with system requirements. Ensure compatibility with horizontal through-hole mounting standards. Check for any recent product change notices or obsolescence alerts from SCHURTER Inc. to avoid supply chain disruptions.

Common Mode Chokes Selection Notes

Select this component when designing single-phase systems requiring significant common mode noise attenuation at high currents. The 2.35 mH inductance offers effective filtering for standard power frequencies. The low DC resistance minimizes power loss in high-current paths. Ensure the PCB layout accommodates the horizontal pin configuration and sufficient clearance for thermal management during continuous 25 A operation.

Common Mode Chokes Part Context

This component belongs to the DKIH series of compensated high-current chokes manufactured by SCHURTER Inc. The series is characterized by its ability to handle substantial DC currents while maintaining effective common mode impedance. These chokes are integral to power entry modules and standalone filter stages where EMI compliance is critical for single-phase AC/DC conversion systems.
