Fixed Inductors Procurement Notes

Verify the specific suffix designation against official documentation, as variations such as -VM or -SM indicate different physical dimensions and mounting orientations within the same electrical family. Confirm RoHS compliance status directly from the manufacturer datasheet prior to integration, as regulatory markings may vary by production batch.

Fixed Inductors Selection Notes

Select this component when a vertical form factor is required for space-constrained power designs. Ensure the 3.93 A current rating aligns with the circuit's peak load requirements. Compare physical footprint constraints against horizontal mount alternatives if board height restrictions are critical to the assembly process.

Fixed Inductors Part Context

This part belongs to the PTKM series of leaded power inductors manufactured by Delevan. The series utilizes ferrite toroidal cores to provide high efficiency and low noise characteristics. These components are designed for through-hole technology applications in industrial and commercial power conversion equipment.

Fixed Inductors Replacement Considerations

Direct substitutes include PTKM50R-50 and PTKM50-50VM. Verify that alternative part numbers match the required 50 uH inductance and 3.93 A current handling capabilities before implementation.
