Overview
The Triad Magnetics F28-700 is a board-mount power transformer featuring a laminated core and through-hole termination. It supports dual primary voltages of 115V and 230V. The secondary winding provides parallel 14V at 0.700A or series 28V at 0.700A. This component utilizes a split bobbin design for PC board applications and carries UL/cUL certification.
Feature Summary
- Split bobbin construction designed for versatile printed circuit board mounting
- Dual primary voltage capability supporting both 115V and 230V input configurations
- Certified for safety compliance with UL and cUL standards
Applications
- General purpose AC to DC power supply circuits
- Industrial control panel power distribution
- Electronic equipment requiring isolated low-voltage DC rails
Procurement Notes
Verify the specific suffix (e.g., -C2) against the datasheet to confirm pinout and insulation class compatibility. Ensure the selected variant matches the required PCB footprint and terminal style. Cross-reference manufacturer documentation for exact lead times and RoHS status before finalizing procurement orders.
Selection Notes
Select this model when a compact, board-mounted solution is required for 28V center-tapped applications. Confirm that the 0.700A current rating meets the load requirements. Verify that the through-hole package fits the available PCB space and that the operating frequency aligns with the system design specifications.
Part Context
This component belongs to the Triad Magnetics F28 series of split bobbin transformers. These units are engineered for high reliability in space-constrained environments. The series offers various voltage and current combinations while maintaining consistent physical dimensions and mounting characteristics across different ratings.
Replacement Considerations
The F28-700-C2 is a documented variant within the same series. Verify if the -C2 suffix indicates identical electrical performance or specific packaging differences. Ensure any substitute maintains the same 6-pin configuration and split bobbin architecture.
