F12-090

Overview

The Triad Magnetics F12-090 is a laminated core power transformer designed for through-hole mounting. It features a single primary winding rated for 115V input and dual secondary windings providing 6.3V or 12.6V outputs depending on configuration. The unit delivers a maximum power of 1.1VA, with current ratings of 180mA in parallel mode or 90mA in series mode. It offers 2500Vrms isolation voltage and utilizes PC pin termination for PCB integration.

Feature Summary

• Utilizes Split Pack split bobbin construction for enhanced versatility in printed circuit board applications.
• Provides dual secondary winding configurations to support both parallel and series output connections.
• Features laminated core design optimized for standard power transformation tasks.

Applications

• Low-power electronic equipment requiring Class 2 safety isolation
• Control circuits utilizing split bobbin transformer architecture
• PCB-mounted power supply stages for consumer electronics

Procurement Notes

Verify the specific suffix (e.g., -C2) against your Bill of Materials, as it may indicate UL/cUL Class 2 certification or specific mounting variations. Confirm that the 115V primary rating matches your local mains voltage requirements. Ensure the 1.1VA power budget accommodates peak load currents without exceeding thermal limits. Check physical dimensions against available PCB real estate before finalizing procurement.

Selection Notes

Select this component when a compact, low-power solution with split bobbin construction is required for PCB mounting. It is suitable for designs needing 1.1VA capacity with flexible secondary voltage options. Consider alternative models if higher power ratings or different primary voltages are necessary. Verify that the through-hole package fits your assembly process constraints.

Part Context

This part belongs to the Triad Magnetics Split Pack series, which emphasizes versatility for board-level power applications. The F12-090 specifically addresses needs for small form-factor transformers with reliable isolation characteristics. It serves as a foundational component in various low-voltage AC/DC conversion systems where space efficiency is critical.

Replacement Considerations

The Tamura 3FS-212 is documented as a direct substitute. Verify compatibility regarding pinout, physical dimensions, and electrical specifications before substitution. Other similar parts exist but require careful evaluation of their specific ratings against the original design requirements.
