Overview
The VPH5-1200-R is a surface-mount switching converter transformer manufactured by Eaton Electronics Division. It features an inductance of 173 µH with a tolerance of ±30%. The device has a maximum DC current rating of 0.14 A and a DC resistance of 0.0711 Ω. Key physical dimensions include a height of 1.70 mm, width of 0.235 mm, and length of 98.4 mm. The component is designed for isolation applications within switch-mode power supply circuits.
Feature Summary
- Surface mount construction for automated assembly
- High-density design suitable for space-constrained PCB layouts
- Isolation capability for switch-mode power supplies
Applications
- Switch-mode power supply (SMPS) transformers
- Industrial control systems
- Commercial electronic equipment
Procurement Notes
Verify the specific datasheet version to confirm electrical parameters and mechanical tolerances match the design requirements. Ensure the surface-mount package dimensions align with the PCB footprint. Confirm that the 0.14 A current rating and 173 µH inductance are sufficient for the target application's operational conditions before finalizing procurement.
Selection Notes
Select this component when a compact, surface-mount isolation transformer is required for low-current SMPS designs. The 173 µH inductance and 0.14 A current limit define its operational range. Consider the 1.70 mm height constraint for vertical clearance. Compare against other VP series variants if different inductance or current ratings are needed for the specific power stage.
Part Context
The VPH5-1200-R belongs to the VP Versa-Pac series of inductors and transformers from Eaton Electronics Division. This series focuses on providing high-performance magnetic components in compact packages for modern electronics. The part integrates core and winding technologies optimized for surface-mount processing, supporting efficient energy storage and isolation in power conversion topologies.
Replacement Considerations
Consult the official Eaton VP series documentation for direct cross-references. Verify that any substitute maintains identical inductance, current rating, and dimensional constraints. Ensure the replacement part supports the same isolation requirements and surface-mount mounting style.
