Procurement Notes
Verify the specific secondary configuration required for your design, as the part supports both parallel and series outputs. Confirm that the through-hole footprint matches your PCB layout constraints. Ensure the 115V primary input aligns with your source voltage. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Validate thermal requirements against the 7.5VA power rating.
Selection Notes
Select this component when a compact laminated transformer with flexible secondary output options is needed. It suits applications requiring 12.6V or 25.2V outputs from a 115V source. Consider the physical size and weight limitations of your enclosure. Evaluate if the 7.5VA power capacity meets the load demands. Compare against other Triad Magnetics models if different voltage ratings or core types are preferred.
Part Context
This model belongs to the Triad Magnetics F-series of power transformers. These components are widely used in industrial and commercial electronics where reliable AC voltage transformation is essential. The F-158XP specifically targets applications needing versatile secondary voltages within a standard through-hole form factor.
Replacement Considerations
Consult official Triad Magnetics documentation for direct substitutes. Verify electrical parameters such as VA rating, voltage ratios, and current capacities before swapping. Ensure mechanical dimensions and pinout compatibility match the existing design.
FAQ
Can the secondary windings be used simultaneously?
Yes, the dual secondary windings can be configured for either parallel operation (12.6V at 600mA) or series operation (25.2V at 300mA).
