Common Mode Chokes Procurement Notes

Verify the specific suffix '0103' against the manufacturer's official datasheet to confirm the exact inductance value and tolerance specifications. Ensure the through-hole footprint matches the PCB design requirements for the vertical 4-pin configuration. Confirm that the 1A current rating aligns with the operational load conditions of the target circuit to prevent saturation or overheating during procurement.

Common Mode Chokes Selection Notes

Select this component when a compact, magnetically compensated choke is required for 2-line power filtering in AC applications. The choice depends on the need for low DCR and high common mode rejection in a through-hole format. Consider the physical dimensions and lead spacing compatibility with existing assembly processes before finalizing the selection for power line noise suppression tasks.

Common Mode Chokes Part Context

This part belongs to the DKFP series of magnetically compensated chokes manufactured by Schurter Inc. The series is characterized by its compact size and ability to handle common mode noise in power lines. The DKFP-A22A-0103 variant specifically targets applications requiring robust interference attenuation in standard voltage ranges, offering a reliable passive filtering solution within the broader product family.

Common Mode Chokes Replacement Considerations

Consult the official Schurter cross-reference documentation for verified substitute part numbers. Do not assume interchangeability based on similar ratings alone; verify electrical parameters and mechanical fitment against the original specification sheet.
