DKFP-C22C-D827

Common Mode Chokes Overview

The DKFP-C22C-D827 is a current compensated common mode choke from the Schurter DKFP series, designed for through-hole PCB mounting. It features an inductance of 27 mH and supports a maximum DC current of 800 mA. The component exhibits a typical DC resistance of 520 mOhms. It operates within a temperature range of -40°C to +125°C and has physical dimensions of 23 mm length, 22 mm width, and 13.5 mm height.

Common Mode Chokes Feature Summary

• Provides magnetic compensation to minimize external magnetic field emission
• Designed for effective noise suppression in single-phase applications
• Compact form factor suitable for space-constrained PCB layouts

Common Mode Chokes Applications

• Noise filtering in AC power input circuits
• Electromagnetic compatibility (EMC) enhancement in electronic devices
• Common mode interference suppression in consumer electronics

Common Mode Chokes Procurement Notes

Verify the specific suffix D827 against official Schurter documentation to confirm the 27 mH inductance and 800 mA rating. Ensure the through-hole package style matches the target PCB footprint. Confirm that the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and availability status.

Common Mode Chokes Selection Notes

Select this component when a high-inductance common mode choke is required for low-current AC lines. The 27 mH value offers significant attenuation at lower frequencies compared to standard chokes. The 800 mA current rating suits light-load applications. Consider the 520 mOhm resistance impact on voltage drop. The compact size allows integration into dense circuit boards without compromising thermal performance.

Common Mode Chokes Part Context

This component belongs to the DKFP series of current compensated chokes manufactured by Schurter Inc. These components are engineered to reduce electromagnetic interference while maintaining a small physical profile. The series utilizes specific core materials to achieve high inductance values in a through-hole package, distinguishing it from surface-mount alternatives or uncompensated filter designs.

Common Mode Chokes Replacement Considerations

Direct substitutes include other DKFP series variants such as DKFP-C22C-024K or DKFP-C22C-1N6Q, provided their electrical ratings align with the circuit requirements. Verify pinout compatibility and mechanical dimensions before substitution.
