Common Mode Chokes datasheet and documents for DFKF-28-0004

DFKF-28-0004

Common Mode Chokes Overview

The DFKF-28-0004 is a magnetically compensated, single-phase common mode choke manufactured by SCHURTER Inc. It features through-hole (THT) radial terminals and a flat design with the inductor horizontally positioned within the housing. The component provides attenuation of common mode interferences for applications up to 440 VAC. Rated current ranges from 0.4 A to 6.3 A at Ta 40 °C, with rated inductance between 0.6 mH and 40 mH and a tolerance of -30% +50%. It operates at frequencies from 50 Hz to 400 Hz.

Common Mode Chokes Feature Summary

Magnetically compensated design for effective common mode interference attenuation
Flat physical profile with horizontally positioned internal inductor
Through-hole mounting with radial four-lead configuration

Common Mode Chokes Applications

Attenuation of common mode interferences
Switching power supplies
DC drives and stepper motor controls
Chopper amplifiers

Common Mode Chokes Procurement Notes

Verify the specific inductance value and rated current required for the application against the datasheet, as the DFKF series offers a wide range of variants. Confirm that the through-hole package dimensions fit the PCB layout. Check for RoHS3 compliance status if environmental regulations apply to the final assembly.

Common Mode Chokes Selection Notes

Select this component when a low-profile, magnetically compensated choke is needed for single-phase AC lines up to 440 VAC. Ensure the operating frequency falls within the 50-400 Hz range. Verify that the thermal performance meets requirements for the expected ambient temperature and load current.

Common Mode Chokes Part Context

The DFKF-28-0004 belongs to the DFKF series of suppression chokes designed for general-purpose noise reduction. These components are engineered for robust performance in industrial and commercial electronic equipment requiring reliable electromagnetic compatibility.
