Fixed Inductors Procurement Notes

Verify the manufacturer designation as API Delevan or simply Delevan when sourcing components. Confirm the specific suffix H indicates horizontal mounting orientation distinct from vertical variants. Ensure the ordering quantity aligns with standard factory packaging multiples to avoid partial shipment issues during procurement processing.

Fixed Inductors Selection Notes

Select this component when horizontal spatial constraints require a low-profile toroidal choke design. The 250 uH value suits moderate frequency noise attenuation requirements. Verify that the 2.07 A current rating meets the circuit's operational demands without saturation. Compare physical footprint dimensions against available PCB real estate before finalizing the design integration.

Fixed Inductors Part Context

This part belongs to the PTHFR-H series of toroidal power chokes manufactured by Delevan. The series utilizes shielded toroidal cores to minimize electromagnetic interference leakage. These components are categorized under common mode chokes and filters within the broader inductor and choke product family.
