Fixed Inductors Procurement Notes

Verify the exact part number against manufacturer documentation to ensure correct inductance value and tolerance. Confirm that the unshielded construction aligns with your electromagnetic interference (EMI) constraints. Check RoHS compliance status if required by your regional regulations. Ensure PCB footprint dimensions match the specified non-standard package size before finalizing the design.

Fixed Inductors Selection Notes

Select this component when a high inductance value is required in a compact form factor. The unshielded nature makes it suitable for applications where magnetic coupling with other components is acceptable or desired. Verify that the 380 mA current rating meets the peak load requirements of the target circuit. Consider thermal management strategies given the 2.53 Ohm DC resistance.

Fixed Inductors Part Context

This component belongs to the ASPI-0804T series of power inductors from Abracon. The series offers various inductance values and current ratings within similar physical footprints. These inductors are designed for commercial, transportation, medical, and industrial applications requiring high efficiency and power density.

Fixed Inductors Replacement Considerations

Direct substitutes include other ASPI-0804T variants with identical electrical parameters. Cross-referencing with other manufacturers' 0804T-sized unshielded wirewound inductors may provide alternatives, provided current and resistance specifications are met.
