Procurement Notes
Verify the manufacturer part number against official Eaton documentation to ensure authenticity. Confirm that the specified electrical parameters match system requirements. Check for RoHS compliance status as indicated in the datasheet. Ensure the operating temperature range aligns with the intended application environment. Validate package dimensions for PCB footprint compatibility.
Selection Notes
Select this component based on its specific 8.5 µH inductance value and 0.92 A current rating. Consider the 0.344 Ω DC resistance for efficiency calculations. Evaluate the 12.9 x 9.2 mm footprint against available board space. Ensure the -40°C to +85°C operating range meets environmental constraints. Compare performance against alternative SMD power inductors if higher current or different inductance is required.
Part Context
This component belongs to the VP Versa-Pac series of power inductors from Eaton Electronics. The series offers various inductance values and current ratings for different power management applications. The VPH1-0059-R specifically targets moderate current applications requiring compact surface-mount solutions. It is distinct from RF inductors or transformers in the same product family.
Replacement Considerations
Consult Eaton's official cross-reference tools for verified substitutes. Ensure any replacement matches the 8.5 µH nominal inductance and 0.92 A current rating. Verify dimensional compatibility with the existing PCB footprint. Confirm equivalent DC resistance and temperature specifications.
