F12-090-C2

Overview

The Triad Magnetics F12-090-C2 is a Class 2 power transformer featuring a laminated core and through-hole PC pin termination. It supports dual primary voltages of 115V and 230V at 50/60Hz. The secondary configuration provides parallel output of 9V at 180mA or series output of 18V at 90mA. Rated at 1.1VA, it offers 2500Vrms isolation voltage and measures 34.93mm in length, 28.58mm in width, and 23.80mm in maximum height.

Feature Summary

• Nonconcentrically wound design optimized for printed circuit board applications
• Split Pack construction with side-by-side primary and secondary windings
• Class 2 safety rating compliant with UL standards

Applications

• Low-power consumer electronics requiring isolated DC supplies
• Industrial control systems utilizing Class 2 circuits
• Medical equipment adhering to safety isolation requirements

Procurement Notes

Verify the specific datasheet version (e.g., FS12-090-C2-B) against your schematic requirements. Confirm that the 1.1VA rating and 2500Vrms isolation meet your system's electrical safety standards. Ensure physical dimensions fit within the designated PCB footprint and enclosure constraints before finalizing component selection.

Selection Notes

Select this model when a compact, low-power transformer is needed for Class 2 isolated power supplies. The nonconcentric winding reduces capacitive coupling between windings, which is beneficial for noise-sensitive applications. Verify that the 115V/230V primary input matches the available line voltage in the target region.

Part Context

This component belongs to the Split Pack™ series of Class 2 power transformers manufactured by Triad Magnetics. The series utilizes laminated cores and is designed specifically for through-hole mounting on printed circuit boards. These transformers are engineered to provide reliable isolation for low-voltage secondary circuits derived from standard AC mains inputs.

Replacement Considerations

Consult official manufacturer substitution guides for verified equivalents. Generic replacements must match the 1.1VA power rating, 2500Vrms isolation, and physical package dimensions to ensure compatibility.
