DKIH-3242-20D5

Common Mode Chokes Overview

The DKIH-3242-20D5 is a single-phase, current-compensated common mode choke from the Schurter DKIH series. Designed for through-hole PCB mounting, it features radial terminals and an unshielded construction. The component supports a maximum DC current of 20A with a typical DC resistance of 2.5mOhms. It provides an inductance of 0.50mH per line with a tolerance range of -30% to +50%. The self-resonant frequency is specified at 7.2MHz. Operating temperatures range from -40°C to +100°C, with physical dimensions including a height of 31mm and a diameter of 53mm.

Common Mode Chokes Feature Summary

• Current compensated design for effective EMI noise suppression in power applications
• Open structure providing lightweight and compact form factor for PCB integration
• Radial through-hole termination suitable for standard assembly processes

Common Mode Chokes Applications

• Single-phase power supply input filtering
• Electronics protection against conducted interference
• PCB-mounted EMI suppression in industrial equipment

Common Mode Chokes Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm electrical parameters such as inductance and current ratings. Ensure the through-hole package style matches the target PCB footprint. Confirm RoHS compliance status if required by the end product specifications. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Common Mode Chokes Selection Notes

Select this component when high current handling up to 20A is required in a single-phase configuration. The low DC resistance minimizes power loss compared to shielded alternatives. Consider the open design benefits for thermal management and weight reduction. Verify that the unshielded nature meets the electromagnetic compatibility requirements of the final application environment.

Common Mode Chokes Part Context

This component belongs to the DKIH series of high-current chokes from Schurter. The series expands the range of current-compensated chokes for PCB mounting, covering rated currents 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

Check the DKIH-3252-324Q-NK for higher current capacity (32A) or the DKIH-3242-257K-NK for alternative inductance values within the same series. Ensure mechanical dimensions and terminal spacing remain compatible with the existing PCB layout before substitution.
