Fixed Inductors Procurement Notes

Verify the specific suffix 'R' and '59H' against official datasheets to confirm the horizontal radial lead orientation and shielding status. Confirm RoHS compliance requirements as specifications may vary by production batch. Ensure the selected variant matches the required 14.5 A current rating and 10 µH inductance for the target design.

Fixed Inductors Selection Notes

Select this component when high current capacity and low DC resistance are critical for power efficiency. The shielded design is preferred for noise-sensitive environments compared to unshielded alternatives. Verify that the physical footprint accommodates the 27.94 mm diameter and 12.06 mm height constraints within the enclosure.

Fixed Inductors Part Context

This part belongs to the API Delevan PTKMR series of fixed power inductors. These components are engineered for robust performance in industrial and commercial power electronics.
