• PCB-mounted current compensation circuits
• High current filtering in industrial electronics

Common Mode Chokes Procurement Notes

Verify the specific part number suffix against official Schurter documentation to confirm exact inductance and tolerance values. Ensure the procurement channel provides valid RoHS compliance certificates. Confirm that the supplier source matches the manufacturer's authorized distribution network to guarantee component authenticity and traceability.

Common Mode Chokes Selection Notes

Select this component for single-phase applications requiring high current handling up to 50 A. The low DC resistance minimizes power loss in high-current paths. Verify that the PCB layout accommodates the radial lead spacing and physical dimensions. Consider the operating temperature range when designing thermal management strategies for enclosed environments.

Common Mode Chokes Part Context

This component belongs to the DKIH series of compensated high current chokes manufactured by Schurter Inc. The series offers various configurations for single and three-phase applications with rated currents ranging from 10 to 50 amperes. These chokes are engineered to suppress EMI noise generated by power applications directly on the printed circuit board.

Common Mode Chokes Replacement Considerations

The DKIH-3252-506J-NK is a similar single-phase compensated choke in the same series but differs in inductance value (1.4 mH vs 150 µH). Substitution requires verification of circuit compatibility due to significant differences in impedance characteristics.
