F-371P

Overview

The Triad Magnetics F-371P is a laminated core power transformer designed for through-hole mounting. It features a primary voltage rating of 115V or 230V and provides dual secondary outputs: 6.3V at 4A and 12.6V center-tapped at 2A. The unit has a total power rating of 24VA and supports an isolation voltage of 1500Vrms. Operating temperatures range from -40°C to 85°C, with physical dimensions of 1.63 inches in length, 1.38 inches in height, and 0.94 inches in width.

Feature Summary

• Dual secondary winding configuration providing independent 6.3V and 12.6V center-tapped outputs
• Laminated core construction optimized for standard AC line frequency operation
• High isolation capability rated at 1500Vrms between windings
• Through-hole PCB mounting style for secure mechanical attachment

Applications

• Power supply units requiring multiple DC voltage rails
• Audio equipment amplifiers utilizing split-rail power architectures
• Industrial control systems needing isolated AC-to-AC conversion
• General-purpose electronic devices requiring 115V/230V input compatibility

Procurement Notes

Verify the specific pinout configuration against your circuit schematic before integration, as terminal arrangements can vary by manufacturing batch. Confirm that the 24VA power rating meets the peak current demands of your load during transient conditions. Ensure the operating environment remains within the specified -40°C to 85°C temperature range to maintain performance integrity and longevity. Check for RoHS compliance status if required by your assembly standards.

Selection Notes

Select this component when a single transformer must provide two distinct secondary voltages from one primary source. The 24VA rating suits low-to-medium power applications where space constraints favor a single magnetic component over separate transformers. Consider the through-hole form factor if surface-mount alternatives are unavailable or if mechanical robustness is prioritized. Validate that the 1500Vrms isolation meets safety regulatory requirements for your target market.

Part Context

This transformer belongs to Triad Magnetics' general-purpose power transformer lineup, characterized by laminated steel cores and standardized pin configurations. These components are widely used in consumer electronics and industrial equipment where reliable AC voltage transformation is required. The F-series typically denotes standard plug-in or PCB mount designs intended for mass production environments.

Replacement Considerations

Direct substitutes include other 24VA transformers with identical 115V/230V primary and matching 6.3V@4A / 12.6V@2A secondary specifications. Verify physical footprint compatibility, specifically the 1.63 x 1.38 inch dimensions, to ensure board fit. Cross-reference pin assignments carefully, as equivalent parts may differ in terminal layout despite electrical similarity.
