Common Mode Chokes datasheet and documents for DKFP-A21A-D312
Common Mode Chokes Overview
The DKFP-A21A-D312 is a magnetically compensated common mode choke from the Schurter DKFP series, designed for through-hole mounting. It features a two-line configuration with an inductance of 12 mH per line and a maximum DC current rating of 0.3 A. The component exhibits a typical DC resistance of 1.28 Ohms and operates within a temperature range of -40°C to +125°C.
Common Mode Chokes Feature Summary
- Magnetically compensated design reduces overall magnetic field interference
- Compact form factor suitable for space-constrained PCB layouts
- Through-hole termination ensures robust mechanical stability
Common Mode Chokes Applications
- Noise suppression in low-current power supply circuits
- EMI filtering in compact electronic devices
- Signal integrity protection in sensitive measurement equipment
Common Mode Chokes Procurement Notes
Verify the specific suffix D312 against official Schurter documentation to confirm exact electrical tolerances and pinout configurations. Ensure compatibility with existing board footprints and thermal management requirements before finalizing procurement decisions.
Common Mode Chokes Selection Notes
Select this component when low current noise suppression is required in a compact package. The 0.3 A rating limits suitability to low-power applications. Verify that the 12 mH inductance meets the target frequency attenuation requirements for the specific circuit design.
Common Mode Chokes Part Context
This part belongs to the DKFP series of current-compensated noise suppression chokes. These components are engineered to provide effective electromagnetic interference reduction while maintaining a small physical footprint, distinguishing them from standard uncompensated common mode chokes.
Common Mode Chokes Replacement Considerations
Consult official Schurter substitution guides for verified equivalents. Generic replacements may not match the specific magnetic compensation characteristics or thermal performance of the original component.
