DKFP-B21B-D810

Common Mode Chokes Overview

The DKFP-B21B-D810 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 a nominal inductance of 10 mH per winding (2x10 mH) and a maximum DC current rating of 0.8 A. The component utilizes a ferrite core to achieve a self-resonant frequency of 450 kHz and maintains a maximum DC resistance of 336 mohms. It operates within a temperature range of -40°C to +125°C and measures 18.5 mm in length, 18 mm in width, and 13 mm in height.

Common Mode Chokes Feature Summary

• Provides magnetic compensation to minimize inductance variation under high differential currents
• Utilizes a compact case type 2B design suitable for space-constrained printed circuit board applications
• Engineered for effective noise suppression in single-phase circuits

Common Mode Chokes Applications

• Noise suppression in single-phase power supplies
• Electromagnetic interference filtering in consumer electronics
• Common mode noise reduction in industrial control systems

Common Mode Chokes Procurement Notes

Verify the specific suffix D810 against official Schurter documentation to confirm the 10 mH inductance and 0.8 A current rating. Ensure the through-hole package dimensions match the target PCB footprint. Confirm RoHS compliance status via the manufacturer's latest datasheet or environmental declaration before finalizing procurement specifications.

Common Mode Chokes Selection Notes

Select this component when a current-compensated choke is required to maintain stable common mode impedance during high differential current loads. The 0.8 A rating and 10 mH inductance suit applications needing moderate noise attenuation without significant voltage drop. Verify that the through-hole mounting style aligns with the assembly process and that the operating temperature range meets the environmental requirements.

Common Mode Chokes Part Context

This part belongs to the DKFP series of magnetically compensated chokes manufactured by Schurter Inc. These components are specifically engineered to address common mode noise while minimizing the impact of differential currents on inductance values. The series offers various current ratings and inductance options to support diverse electromagnetic compatibility requirements in electronic equipment.

Common Mode Chokes Replacement Considerations

The DKFP-B22B-D810 shares identical electrical parameters including 10 mH inductance and 0.8 A current rating but differs in physical case dimensions. Verify mechanical fit if substituting between B21B and B22B variants. No other direct substitutes are confirmed in public documentation.
