F20-1000

Overview

The Triad Magnetics F20-1000 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 parallel 10V or series 20V outputs at full load. Maximum output currents are specified as 2A in parallel configuration and 1A in series configuration, resulting in a maximum power rating of 20VA. The unit utilizes PC pin termination and measures 57.15mm in length by 47.63mm in width, with a maximum installation height of 36.50mm. It offers an isolation voltage of 2500Vrms.

Feature Summary

• Split bobbin construction for enhanced versatility in PCB applications
• Dual secondary windings supporting flexible parallel or series output configurations
• Compliance with Class 2/3 safety standards

Applications

• General purpose AC to DC power supply circuits
• Industrial control equipment requiring isolated power
• Consumer electronics utilizing split bobbin transformers

Procurement Notes

Verify the specific suffix against the required datasheet revision, as variants like F20-1000-C2 may differ in packaging or regulatory compliance status. Confirm that the single primary winding specification aligns with the target 115V input requirement, distinguishing it from dual-primary models such as the FS20-1000. Ensure the through-hole package matches the printed circuit board layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a single 115V primary input is required alongside flexible secondary voltage options. The 20VA rating suits low-to-medium power applications. Verify that the 2500Vrms isolation voltage meets system safety requirements. Consider the physical dimensions of 57.15mm x 47.63mm for adequate board spacing. This model is distinct from the FS20-1000 which supports dual primary voltages.

Part Context

The F20-1000 belongs to the Split Pack™ series of power transformers manufactured by Triad Magnetics. This series is characterized by split bobbin designs intended to improve coupling and reduce leakage inductance for efficient PCB mounting. The part is classified under Class 2/3 safety standards, indicating its suitability for limited energy circuits within electronic assemblies.

Replacement Considerations

Public confirmed substitute part numbers include Hammond Manufacturing 162H20 and Signal Transformer DST-6-20. These alternatives are listed as similar replacements but require verification of electrical parameters and mechanical fit.
