F3-12

Overview

The Triad Magnetics F3-12 is a laminated core power transformer designed for chassis mounting. It features a split bobbin construction with an 115V primary winding and a 12.6V center-tapped secondary output. The unit provides a maximum power rating of 2.4VA, supporting a secondary current of 0.200A at the full 12.6V configuration or 0.400A from each half-winding to the center tap. It operates on 50Hz or 60Hz frequencies and includes quick pack lugs for terminal connection.

Feature Summary

• Chassis mount design with split bobbin construction
• Laminated core for efficient power transformation
• Center-tapped secondary winding for dual polarity applications
• Integrated lugs for rapid terminal connection

Applications

• Audio equipment power supplies
• Industrial control systems
• General purpose AC to DC conversion circuits

Procurement Notes

Verify the specific voltage rating and physical dimensions against the official Triad Magnetics datasheet before integration. Confirm that the chassis mounting holes align with the enclosure design. Ensure the operating frequency matches the system requirement of 50Hz or 60Hz. Check for any updated regulatory compliance markings such as UL/cUL certification status in the latest documentation.

Selection Notes

Select this component when a low-power, chassis-mounted solution is required for 115V input systems. The 2.4VA rating suits light loads where space constraints favor a compact laminated core design over toroidal alternatives. Consider the split bobbin structure if enhanced isolation between windings is necessary for safety compliance in sensitive electronic assemblies.

Part Context
