F-3142XP

Overview

The Triad Magnetics F-3142XP is a board-mount power transformer with a 4.5 VA rating. It features dual primary windings for 115V or 230V operation and dual secondary windings providing 7.5V at 600mA in parallel or 15V at 300mA in series. The unit utilizes an 8-terminal pin flange mount through-hole configuration.

Feature Summary

• Dual primary winding design supporting 115V and 230V input configurations
• Dual secondary winding architecture allowing flexible voltage output combinations
• High isolation rating of 1500Vrms between windings
• Through-hole mounting style with pin flange terminals for secure PCB attachment

Applications

• Industrial control systems requiring isolated power supplies
• Audio equipment power stages needing specific voltage taps
• General purpose electronic devices utilizing standard AC mains inputs

Procurement Notes

Verify the specific datasheet version to confirm terminal pin dimensions and spacing, as manufacturing revisions may occur. Ensure the selected mounting hole pattern on the PCB matches the physical flange specifications provided in the official mechanical drawings. Confirm insulation class requirements align with the target application's safety standards before finalizing the component selection.

Selection Notes

Select this component when a compact 4.5 VA transformer is required for dual-voltage primary applications. The dual secondary configuration offers flexibility for circuits needing multiple voltage rails or higher current capabilities through parallel connection. Consider the physical footprint and through-hole mounting constraints during the PCB layout phase to ensure proper clearance and mechanical stability.

Part Context

This part belongs to the Triad Magnetics F-series of power transformers, which are designed for general-purpose industrial and commercial applications. The series emphasizes reliability and compliance with international safety standards. The F-3142XP specifically addresses needs for moderate power levels with versatile input/output configurations.

Replacement Considerations

Direct substitutes include other Triad Magnetics models within the same F-series offering similar VA ratings and mounting styles. Verify that any replacement maintains the same 1500Vrms isolation rating and compatible physical dimensions for existing PCB footprints.
