DKFP-B21B-D527

Common Mode Chokes Overview

The DKFP-B21B-D527 is a current compensated noise suppression choke from the Schurter DKFP series, designed for through-hole PCB mounting. It features a single channel configuration with an inductance of 27 mH and a maximum DC current rating of 500 mA. The component exhibits a maximum DC resistance of 0.841 ohms and operates within a temperature range of -40°C to +125°C.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression through magnetically compensated choke technology
• Supports surface or board mounting via through-hole termination style
• Maintains performance across extended industrial temperature environments

Common Mode Chokes Applications

• Electromagnetic interference filtering in compact electronic assemblies
• Noise suppression in low-current DC power supply circuits
• Signal integrity protection in sensitive measurement equipment

Common Mode Chokes Procurement Notes

Verify the specific part number DKFP-B21B-D527 against official Schurter documentation to confirm electrical parameters such as 27 mH inductance and 500 mA current rating. Ensure compatibility with through-hole PCB layouts and verify operating temperature requirements match the -40°C to +125°C specification before procurement.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring compact common mode chokes with moderate inductance values. The 500 mA current rating suits low-power applications, while the through-hole package facilitates manual assembly or wave soldering processes where surface mount options are unsuitable.

Common Mode Chokes Part Context

This component belongs to the DKFP series of current compensated chokes manufactured by Schurter Inc. These devices are engineered for noise suppression in space-constrained environments, offering high inductance density relative to their physical footprint compared to standard common mode filters.

Common Mode Chokes Replacement Considerations

Cross-reference with other DKFP series variants like DKFP-B21B-1K6Q or DKFP-B22B-D439 only if electrical parameters align. Verify pinout and mechanical dimensions match existing PCB footprints before substituting.
