Procurement Notes
Verify the specific suffix designation against official Triad Magnetics documentation to confirm exact electrical characteristics and certification status. Ensure the procurement specification matches the required Class 2/3 compliance and frequency range. Cross-reference the part number with the manufacturer's current datasheet to validate availability and technical parameters prior to ordering.
Selection Notes
Select this component when a split bobbin topology is required for PCB-mounted power transformation. The dual secondary configuration is suitable for applications needing two isolated 14V outputs from a 115V primary source. Consider the 2.5VA power rating and physical dimensions to ensure compatibility with the target printed circuit board layout and thermal environment.
Part Context
This model belongs to the Triad Magnetics F28 series of power transformers. These components are characterized by their split bobbin design, which facilitates efficient winding distribution and thermal management. The series is engineered for reliable performance in industrial and commercial electronic applications requiring robust isolation and stable voltage conversion.
Replacement Considerations
Public confirmed substitute part numbers include FS28-085 and VPL28-900. Verify that alternative models match the required 115V primary input, 14V secondary output specifications, and 2.5VA power rating. Confirm that the replacement maintains the necessary Class 2/3 safety certifications and physical mounting constraints for the application.
