DKFP-D21D-0210

Common Mode Chokes Overview

The DKFP-D21D-0210 is a current compensated common mode choke from the Schurter DKFP series, designed for through-hole PCB mounting. It features a single-channel configuration with an inductance of 10 mH and a maximum DC current rating of 2 A. The component exhibits a typical DC resistance of 149 mOhms and operates within a temperature range of -40°C to +125°C. Its compact dimensions are 29 mm in length, 28 mm in width, and 17 mm in height, with a unit weight of approximately 25 g.

Common Mode Chokes Feature Summary

• Provides magnetic compensation to minimize leakage inductance effects in noise suppression applications
• Utilizes a compact radial leaded package suitable for space-constrained printed circuit board designs
• Constructed as an unshielded common mode choke for effective electromagnetic interference filtering

Common Mode Chokes Applications

• Noise suppression in power supply input stages
• Electromagnetic interference filtering for electronic equipment
• Common mode noise reduction in AC/DC converter circuits

Common Mode Chokes Procurement Notes

Verify the specific suffix code against official Schurter documentation to confirm exact electrical parameters, as variations exist within the DKFP family. Ensure compatibility with standard through-hole assembly processes and validate thermal performance requirements against the specified operating temperature range before finalizing procurement decisions.

Common Mode Chokes Selection Notes

Select this component when a low-profile, magnetically compensated choke is required for single-phase noise suppression. The 2 A current rating and 10 mH inductance make it suitable for general-purpose power line filtering where minimal leakage inductance is critical. Confirm that the physical footprint and lead spacing match the target PCB layout constraints.

Common Mode Chokes Part Context

This component belongs to the DKFP series of current compensated chokes manufactured by Schurter. These devices are engineered to provide high common mode attenuation while maintaining low differential mode impedance. The series is widely used in industrial and consumer electronics for meeting regulatory emission standards through effective EMI mitigation.

Common Mode Chokes Replacement Considerations

Consult official Schurter substitution guides for verified alternatives. Generic cross-references may not replicate the specific magnetic compensation characteristics or dimensional tolerances required for proper fit and function.
