DKIH-3237-1010-NK

Common Mode Chokes Overview

The DKIH-3237-1010-NK is a single-phase common mode choke from Schurter's DKIH series, designed for through-hole PCB mounting. It features a radial termination style and operates within a temperature range of -40°C to +100°C. Key electrical specifications include a rated current of 10 A, an inductance of 6.9 mH per winding (2x6.9 mH), and a maximum DC resistance of 10 mOhms. The component has a self-resonant frequency of 2 MHz and physical dimensions of 37 mm diameter by 26 mm height.

Common Mode Chokes Feature Summary

• Provides effective noise suppression for single-phase circuits through high common mode inductance.
• Supports high current applications with a 10 A rated capacity and low DC resistance.
• Utilizes a robust through-hole radial design suitable for standard PCB assembly processes.

Common Mode Chokes Applications

• Electromagnetic interference filtering in single-phase power supplies
• Noise suppression in industrial control systems
• Input stage filtering for AC/DC converters

Common Mode Chokes Procurement Notes

Verify the specific suffix NK against the manufacturer datasheet to confirm exact mechanical and material compliance. Ensure the ordering part number matches the required inductance tolerance and current rating for your circuit design. Cross-reference the Mouser or Schurter official documentation to confirm availability and lead times before finalizing procurement plans.

Common Mode Chokes Selection Notes

Select this component when designing single-phase filters requiring 10 A handling capability and 6.9 mH common mode inductance. Consider the 26 mm height and 37 mm diameter for adequate PCB clearance. Verify that the operating environment stays within the specified -40°C to +100°C range and that the 2 MHz self-resonant frequency aligns with your noise spectrum requirements.

Common Mode Chokes Part Context

This component belongs to the Schurter DKIH series of current compensated noise suppression chokes. These parts are engineered for high-current single-phase applications, offering a balance of compact size and significant noise attenuation capabilities compared to lower-rated alternatives in the same family.

Common Mode Chokes Replacement Considerations

Check Schurter datasheets for other DKIH-3237 variants with matching 10 A ratings and similar inductance values. Ensure any substitute maintains the same radial through-hole footprint and thermal characteristics.
