Fixed Inductors Procurement Notes

Verify the specific ordering suffix matches the required tolerance and packaging format. Confirm that the lead time aligns with project schedules before finalizing orders. Ensure storage conditions remain within the specified humidity limits to maintain component reliability during handling and installation processes.

Fixed Inductors Selection Notes

Select this component when a compact unshielded inductor with high current capability is required. The 3.3 µH value suits specific filtering needs in space-constrained designs. Consider the 87 mΩ resistance for efficiency calculations in low-voltage applications requiring stable performance across wide temperature ranges.

Fixed Inductors Part Context

This part belongs to the OWIHP series of fixed inductors from Ole Wolff Electronics. The series includes various inductance values and current ratings tailored for different power levels. Similar models like the OWIHP0420M-R56 share the same physical footprint and manufacturing technology but differ in electrical specifications.

Fixed Inductors Replacement Considerations

Direct substitutes are not explicitly listed in available documentation. Engineers should evaluate components with matching 3.3 µH inductance, similar current ratings, and compatible SMD footprints. Verify that alternative parts meet the -55°C to +125°C operating temperature requirement.
