DFKF-28-0006

Common Mode Chokes Overview

The DFKF-28-0006 is a magnetically compensated common mode choke manufactured by Schurter Inc. It features a flat design with through-hole terminals and supports rated currents from 0.4 A to 6.3 A at 40 °C ambient temperature. The inductance ranges from 0.6 mH to 40 mH with a tolerance of -30% to +50%. Rated voltage is up to 440 VAC, operating frequency spans 50 Hz to 400 Hz, and the housing material meets UL 94V-0 standards.

Common Mode Chokes Feature Summary

• Magnetically compensated one-phase design for effective attenuation of common mode interferences
• Flat physical profile suitable for space-constrained mounting configurations
• Through-hole terminal construction for standard PCB integration

Common Mode Chokes Applications

• Attenuation of common mode interferences in electronic circuits
• Switching power supplies requiring EMI suppression
• DC drives and stepper motor control systems
• Chopper amplifiers in industrial automation

Common Mode Chokes Procurement Notes

Verify the specific inductance value and current rating required for your application against the available variants within the DFKF series, as parameters vary significantly across the product line. Confirm that the through-hole footprint dimensions match your PCB layout constraints. Ensure the operating environment temperature remains within the specified limits to maintain performance integrity and safety compliance.

Common Mode Chokes Selection Notes

Select this component when a compact, magnetically compensated choke is needed for one-phase applications. Consider the specific inductance range (0.6 mH to 40 mH) and current rating (up to 6.3 A) relevant to your circuit requirements. Verify compatibility with operating frequencies between 50 Hz and 400 Hz and ensure the 440 VAC rated voltage meets system insulation needs.

Common Mode Chokes Part Context

The DFKF-28-0006 belongs to Schurter's DFKF series of magnetically compensated chokes. These components are engineered for general-purpose inductive filtering in single-phase AC/DC environments. The series emphasizes a low-profile form factor while maintaining robust electromagnetic interference suppression capabilities for sensitive electronic equipment.

Common Mode Chokes Replacement Considerations

Direct substitutes may include other Schurter DFKF series variants with matching inductance and current ratings. Cross-reference datasheets for equivalent magnetic compensation characteristics and terminal configurations to ensure functional compatibility without redesigning the PCB footprint.
