Overview
The VPH3-0055-R is a surface-mount power inductor from the Eaton VP Versa-Pac series, designed for switch-mode power supply applications. It features a ferrite core and wirewound construction with an inductance of 9.3 µH ±20%. The component supports a saturation current of 1.02 A and has a DC resistance of 0.14 Ω. Physical dimensions include a height of 3.38 mm and a footprint compatible with standard SMD mounting.
Feature Summary
- Surface-mount design for automated PCB assembly
- Ferrite core construction for efficient magnetic performance
- Optimized for high-frequency switching applications
Applications
- Switch-mode power supplies (SMPS)
- DC-DC converter circuits
- Isolated power transformer stages
Procurement Notes
Verify the specific suffix 'R' against the manufacturer's latest datasheet to confirm tape-and-reel packaging configuration. Ensure compatibility with peak reflow temperature profiles specified for the VP series. Cross-reference the 9.3 µH value with circuit requirements to prevent saturation under load conditions.
Selection Notes
Select this component when space-constrained designs require a low-profile inductor with moderate current handling capabilities. The 3.38 mm height suits applications with strict vertical clearance limits. Evaluate thermal dissipation needs based on the 0.14 Ω DC resistance to ensure efficiency targets are met within the operating environment.
Part Context
This part belongs to Eaton's VP Versa-Pac family, which provides standardized solutions for board-level power conversion. The series emphasizes reliability and compact form factors for modern electronics. The VPH3-0055-R specifically addresses needs for isolated or non-isolated power stages requiring stable inductance values.
Replacement Considerations
Direct substitutes must match the 9.3 µH nominal value, 1.02 A current rating, and similar physical footprint. Verify that alternative components support the same voltage ratings and frequency characteristics. Consult Eaton's official cross-reference guides for validated equivalent parts.
