F-151XP

Overview

The Triad Magnetics F-151XP is a laminated core power transformer designed for board mount applications. It features a single primary winding rated at 115V AC and a dual secondary configuration providing 8.0V center-tapped output at 0.940A, or parallel operation delivering 4.0V at 1.88A. The unit has a power rating of 7.5VA and measures 71.42mm in length, 37.29mm in width, and 41.28mm in height. It utilizes through-hole termination with PC pins and operates within a temperature range of 0°C to +130°C.

Feature Summary

• Dual secondary winding architecture supporting both series center-tapped and parallel current configurations
• Laminated core construction optimized for standard power transformation tasks
• Through-hole mounting style with PC pin terminations for secure PCB integration

Applications

• General purpose power supply circuits requiring isolated AC voltage conversion
• Audio equipment power stages utilizing center-tapped secondary outputs
• Industrial control panels needing robust board-mounted isolation transformers

Procurement Notes

Verify the specific datasheet revision prior to ordering, as electrical characteristics may vary between manufacturing batches. Confirm that the physical dimensions and pin spacing match your printed circuit board layout constraints. Ensure the operating environment remains within the specified thermal limits to maintain performance integrity and safety compliance throughout the product lifecycle.

Selection Notes

Select this component when a 7.5VA capacity is required for 115V primary systems. Choose the F-151XP over other models if through-hole mounting is mandatory rather than surface mount options. Consider the dual secondary flexibility for designs needing either higher current parallel delivery or split-rail series center-tapped supplies without additional complex wiring.

Part Context

This part belongs to the Triad Magnetics F series of power transformers, which are widely used in industrial and commercial electronics. The series emphasizes reliability and standardized form factors for easy integration into existing chassis or panel designs. As a board-mount unit, it bridges the gap between large chassis transformers and smaller signal transformers, offering substantial power handling in a compact footprint.

Replacement Considerations

Consult official manufacturer substitution guides for direct equivalents. Verify that any alternative part matches the 7.5VA rating, 115V primary input, and compatible secondary voltage/current specifications. Ensure mechanical compatibility regarding hole spacing and overall envelope dimensions to fit existing PCB footprints without modification.
