DKFP-C21C-D827

Common Mode Chokes Overview

The DKFP-C21C-D827 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 6.8 mH and a maximum DC current rating of 800 mA. The component exhibits a typical DC resistance of 520 mOhms and operates within a temperature range of -40°C to +125°C. Its self-resonant frequency is specified at 500 kHz, ensuring effective noise suppression in power line applications.

Common Mode Chokes Feature Summary

• Magnetically compensated design reduces leakage inductance for efficient signal integrity
• Compact form factor suitable for space-constrained printed circuit board layouts
• Through-hole termination style provides robust mechanical stability

Common Mode Chokes Applications

• Switching power supplies
• DC drives and stepper motor controls
• Chopper amplifiers

Common Mode Chokes Procurement Notes

Verify the specific suffix D827 against the manufacturer datasheet to confirm the 800mA current rating and 6.8mH inductance values. Ensure the through-hole package dimensions match the target PCB footprint. Cross-reference the thermal operating limits with system requirements before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when low leakage inductance is critical for high-frequency noise attenuation in single-phase circuits. The 800mA rating suits moderate power applications where compact size is prioritized over higher current capacity. Validate that the 520mOhm resistance does not cause excessive voltage drop in the specific circuit design.
