F-156XP

Overview

The Triad Magnetics F-156XP is a power transformer with a 7.5VA rating, designed for industrial applications. It features a single primary winding rated at 115V and dual secondary windings providing 15.0VCT at 0.500A. The unit utilizes PC pin termination for through-hole or flange mounting. Key electrical specifications include a maximum operating temperature of 105°C and an isolation voltage of 1500Vrms. Physical dimensions are 71.42mm in length, 37.29mm in width, and a seated height of up to 41.28mm. The core type is laminated steel, ensuring reliable performance in control circuits.

Feature Summary

• Dual secondary windings support flexible circuit configurations
• PC pin termination enables secure board integration
• Laminated steel core provides stable magnetic coupling

Applications

• Industrial control panels
• Power supply input stages
• Equipment requiring isolated low-voltage AC sources

Procurement Notes

Verify the specific secondary voltage configuration against project requirements, as variants exist within the series. Confirm mounting style compatibility, noting that this model supports both through-hole and flange options. Ensure the PCB footprint matches the PC pin spacing. Check RoHS compliance status if environmental regulations apply to your assembly process. Cross-reference datasheet revision dates to guarantee parameter accuracy during procurement.

Selection Notes

Select this component when a 7.5VA capacity is sufficient for the load. The 115V primary input dictates compatibility with standard North American or similar grid voltages. Consider the physical envelope constraints, as the 41.28mm height may impact enclosure design. Evaluate thermal management needs given the 105°C rating. Compare against other XP series models if different voltage taps or current ratings are required for the specific application topology.

Part Context

This part belongs to the Triad Magnetics XP series of power transformers, which are widely used in general-purpose industrial electronics. The series offers various VA ratings and voltage combinations tailored for control transformers. The F-156XP specifically addresses needs for moderate power isolation with dual secondary outputs, fitting into legacy and modern equipment designs requiring robust, compact magnetic components.

Replacement Considerations

Direct substitutes include the F-152XP for lower power requirements or the F-164XP for different secondary voltage configurations within the same form factor family. Verify that any replacement maintains the 1500Vrms isolation rating and compatible PC pin pitch to ensure mechanical and electrical interchangeability without redesigning the PCB layout.
