F-220U

Overview

The Triad Magnetics F-220U is a laminated core power transformer designed for chassis mounting. It features a single primary winding rated at 115V and a single secondary winding providing 12V at 6A. The unit delivers a maximum power of 72VA with 1500Vrms isolation voltage. Physical dimensions are approximately 95.25mm in length, 53.98mm in width, and 57.15mm in height. Termination is achieved via wire leads.

Feature Summary

• Laminated core construction for efficient magnetic flux transfer
• Chassis mount design with wire lead termination
• Single primary to single secondary winding configuration
• High voltage isolation capability

Applications

• General purpose AC power supply circuits
• Industrial control panel power distribution
• Audio equipment power stages
• Electronic test instrument internal power systems

Procurement Notes

Verify the specific secondary voltage rating required for your application, as datasheets may list variations such as 12V or 12.6V. Confirm that the 72VA power rating aligns with your load requirements. Ensure chassis mounting holes match your enclosure specifications. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Review the datasheet for precise terminal pinout and insulation class details before integration.

Selection Notes

Select this component when a robust, high-current chassis-mounted transformer is needed for 115V input applications. The 6A output current capacity supports substantial loads compared to lower VA units. Consider the physical footprint constraints, as the chassis mount style requires specific panel cutouts. Evaluate thermal management needs given the 72VA dissipation. Compare against isolated vs non-isolated requirements, though this model provides galvanic isolation.

Part Context

The F-220U belongs to Triad Magnetics' standard line of industrial power transformers. It is part of a broader family of chassis-mount units designed for reliability in commercial and industrial environments. Similar models in the series offer different voltage taps or power ratings, allowing designers to scale power delivery while maintaining consistent form factors and mounting styles across product lines.

Replacement Considerations

Direct substitutes include the F-224X, which offers similar chassis mounting but differs in power rating (37.8VA) and secondary voltage (12.6V). Designers should verify that the replacement meets or exceeds the original 72VA requirement and matches the 115V primary specification. Physical dimension compatibility must be confirmed to ensure fit within existing enclosures.
