F120-100

Overview

The Triad Magnetics F120-100 is a split bobbin power transformer designed for PCB mount applications. It features a single primary winding rated at 115 VAC and dual secondary windings providing 120 VCT at 0.100 A. The unit has a 12 VA power rating and supports series (120V/100mA) or parallel (60V/200mA) secondary configurations. It operates within a temperature range of 0°C to +25°C, measures 47.63 mm in length, 39.67 mm in width, and 36.49 mm in height, and includes UL/cUL certification.

Feature Summary

• Split bobbin construction for enhanced isolation
• Dual secondary windings allowing flexible series or parallel output configuration
• Through-hole PCB mounting design

Applications

• Audio equipment power supplies
• Industrial control systems
• Test and measurement instrumentation

Procurement Notes

Verify the specific voltage and current requirements against the datasheet before procurement. Confirm that the operating environment remains within the specified 0°C to +25°C range. Ensure the PCB layout accommodates the through-hole pin spacing and physical dimensions. Check for UL/cUL compliance if required by end-use regulations.

Selection Notes

Select this component when a 12 VA isolated power source is needed with flexible secondary voltage options. The split bobbin design is suitable for applications requiring strict isolation barriers. Consider the thermal limits carefully, as the maximum operating temperature is relatively low compared to standard industrial transformers.

Part Context

This part belongs to the Triad Magnetics F120 series of power transformers. The series offers various power ratings and voltage configurations tailored for general-purpose AC-to-DC power supply stages. The F120-100 specifically addresses needs for moderate power delivery with versatile secondary wiring options.

Replacement Considerations

The Hammond Manufacturing part number 164G120 is listed as a cross-reference substitute. Verify electrical parameters and mechanical fit before substitution.
