F16-1250

Overview

The Triad Magnetics F16-1250 is a laminated core power transformer designed for printed circuit board (PCB) mounting. It features a primary voltage of 115V and a secondary configuration providing 8V at 2.5A in parallel or 16V at 1.25A in series. The unit has a 20VA rating and utilizes a split bobbin construction to minimize inter-winding capacitance. It is UL and cUL recognized for Class 2/3 applications.

Feature Summary

• Split bobbin design reduces inter-winding capacitance for improved signal integrity
• Versatile secondary output options allowing parallel or series connection
• Laminated core construction for efficient power transfer
• PCB mount form factor for direct board integration

Applications

• Audio equipment power supplies
• Industrial control systems
• Consumer electronics requiring isolated power
• Class 2/3 limited energy circuits

Procurement Notes

Verify the specific suffix (e.g., -C2, -B) against your bill of materials, as these may indicate variations in packaging, certification, or terminal configuration. Confirm that the 115V primary voltage matches your input source. Ensure the PCB footprint accommodates the through-hole pin arrangement and physical dimensions of the Split Pack housing before ordering.

Selection Notes

Select this component when a compact, low-capacitance transformer is required for audio or sensitive analog circuits. The split bobbin architecture is critical for minimizing hum and noise coupling. Choose between parallel (8V/2.5A) or series (16V/1.25A) secondary configurations based on the required DC bus voltage and current capacity of the downstream rectifier and filter stage.

Part Context

This model belongs to Triad Magnetics' Split Pack™ series, which specializes in nonconcentrically wound transformers for PC board applications. The series is engineered to address interference issues common in standard concentric windings, making it suitable for high-fidelity and noise-sensitive environments where electromagnetic compatibility is a priority.

Replacement Considerations

Direct replacements must match the 20VA rating, 115V primary, and [email protected] secondary specifications. Verify that any substitute also features a split bobbin design if low capacitance is required. Check pinout compatibility and physical envelope dimensions to ensure fit within the existing PCB layout without modification.
