Fixed Inductors Procurement Notes

Verify the specific revision and RoHS compliance status directly with Eaton Electronics or authorized distributors before procurement. Confirm that the package dimensions and terminal configuration match the target PCB footprint requirements. Ensure the operating environment remains within the specified -40°C to +125°C temperature range to maintain performance integrity.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor with high saturation current is required for space-constrained power designs. Compare the 820 mΩ DC resistance against thermal management capabilities in the final assembly. Consider the physical dimensions of 3.70 mm height when determining board clearance and stacking constraints relative to adjacent components.

Fixed Inductors Part Context

This part belongs to the UNI-PAC 5 series of fixed inductors manufactured by Eaton Electronics. The series provides various inductance values optimized for surface-mount power applications. The UNI-PAC branding indicates a standardized form factor designed for automated placement and consistent electrical performance across the product line.

Fixed Inductors Replacement Considerations

Direct substitutes include other UNI-PAC series inductors with matching 470 µH values, such as the UP4B-471-R or UP2C-471-R, provided their current ratings and physical footprints are compatible with the existing design constraints.
