Overview
The VPH1-0190-R is a surface-mount power inductor from Eaton's VP Versa-Pac series, designed for switching converter applications. It features a ferrite core and wirewound construction with an inductance of 27.4 µH ±20%. The component supports a maximum DC current of 0.29 A and a saturation current of 0.55 A, with a maximum DC resistance of 344 mΩ. It operates within a temperature range of -40°C to +85°C and utilizes a tape-and-reel packaging format.
Feature Summary
- Wirewound ferrite core construction for high-current handling
- Surface-mount design compatible with automated assembly
- Integrated shielding characteristics inherent to the package geometry
Applications
- DC-DC converter output filtering
- Point-of-load (POL) regulation stages
- Power supply input chokes
Procurement Notes
Verify the specific suffix and manufacturer part number against official Eaton documentation to ensure correct electrical specifications. Confirm that the procurement source provides valid traceability and authenticity guarantees. Check for any recent product lifecycle notices or obsolescence warnings directly from the manufacturer before finalizing orders.
Selection Notes
Select this component when a compact surface-mount solution is required for low-power switching converters. Ensure the application current remains below the 0.29 A rating to prevent performance degradation. Verify that the physical footprint and height constraints align with the board layout requirements for the Versa-Pac series dimensions.
Part Context
This part belongs to Eaton's VP Versa-Pac family, which offers shielded power inductors optimized for space-constrained designs. The series provides consistent performance across various inductance values while maintaining a standardized footprint to simplify inventory management and board design processes for power electronics engineers.
Replacement Considerations
Consult Eaton's official cross-reference tools for verified substitutes. Direct replacements must match the 27.4 µH inductance, 0.29 A current rating, and identical mechanical dimensions to ensure compatibility without redesigning the PCB layout.
