Overview
The Eaton VPH1-0102-R is a surface-mount pulse transformer from the VERSA-PAC series, designed for isolated power supply applications. It features a ferrite core and provides 500VAC isolation capability. The component has an inductance of 14.7 µH with a ±20% tolerance. Key electrical parameters include a maximum DC current rating of 0.53 A and a maximum DC resistance of 0.55 Ω. The device operates within a temperature range of -40°C to +125°C and utilizes a standard SMD termination style.
Feature Summary
- Provides galvanic isolation for switched-mode power supplies
- Utilizes a ferrite core for efficient magnetic performance
- Designed for surface-mount assembly processes
Applications
- Isolated DC-DC converter modules
- Switched-mode power supply (SMPS) front ends
- Industrial control system power interfaces
Procurement Notes
Verify the specific datasheet version when ordering, as Eaton may update mechanical dimensions or testing standards over time. Confirm that the 500VAC isolation rating meets your safety compliance requirements. Ensure the operating temperature range of -40°C to +125°C aligns with your thermal design constraints. Cross-reference the pinout and footprint with your PCB layout to prevent assembly errors.
Selection Notes
Select this component when high-frequency isolation is required in compact designs. The 14.7 µH inductance suits moderate power transfer needs. Consider the 0.53 A current limit for load matching. The wide temperature range supports harsh environments. Compare against similar VERSA-PAC models if higher current or different isolation voltages are needed.
Part Context
This part belongs to Eaton's VERSA-PAC line of magnetics, which focuses on miniaturized solutions for modern electronics. The series integrates inductors and transformers into single packages to save board space. The VPH1-0102-R specifically addresses isolation needs in low-to-medium power converters, offering a balance between size and electrical performance.
Replacement Considerations
Consult Eaton's official cross-reference guide for verified substitutes. Generic equivalents may not match the 500VAC isolation or specific inductance tolerances. Verify that any replacement maintains the same SMD footprint and thermal characteristics.
