F48-400

Overview

The Triad Magnetics F48-400 is a laminated core power transformer designed for PCB mounting. It features a single primary winding rated for 115V input and a split bobbin construction with dual secondary windings. The unit provides a center-tapped output of 48.0Vct at 0.400A, delivering a maximum power rating of 20VA. Key electrical specifications include a 2500Vrms isolation voltage and PC pin termination style.

Feature Summary

• Split bobbin design enhances versatility for printed circuit board applications
• Dual secondary windings allow flexible series or parallel output configurations
• Laminated core construction supports standard industrial power requirements

Applications

• General purpose power supply circuits
• Industrial control equipment
• Electronic instrumentation systems

Procurement Notes

Verify the specific datasheet version to confirm exact dimensional tolerances and insulation class ratings. Ensure that the PCB footprint matches the PC pin spacing provided in the official mechanical drawings. Confirm compliance with regional safety standards required for the final assembly before procurement.

Selection Notes

Select this component when a compact, board-mount solution is required for 115V input systems. The dual secondary configuration offers flexibility for creating different voltage rails. Consider the physical size constraints and thermal management needs associated with a 20VA laminated core transformer in the final enclosure design.

Part Context

This part belongs to the Split Pack series from Triad Magnetics, which specializes in transformers optimized for direct PCB integration. The series utilizes split bobbin technology to improve coupling and reduce leakage inductance compared to traditional wound designs.

Replacement Considerations

The FS48-400 is listed as an alternative product by the manufacturer. Verify that the substitute maintains identical pinout, voltage ratings, and form factor compatibility before implementation.
