F-138P

Overview

The Triad Magnetics F-138P is a power transformer with a 1.5 VA rating, designed for through-hole mounting. It features a single primary winding rated at 115V and dual secondary windings providing 2 x 12.6V center-tapped outputs. The unit offers 1500Vrms isolation and operates at 50/60 Hz frequencies.

Feature Summary

• Provides galvanic isolation between primary and secondary circuits
• Supports flexible voltage configuration via series or parallel secondary connections
• Constructed with a bobbin core design for stable performance

Applications

• Drive isolation applications
• Low-power AC to DC power supply circuits
• Industrial control equipment requiring isolated power

Procurement Notes

Verify the specific datasheet version to confirm terminal pinout and insulation class requirements. Ensure the selected component meets the thermal management needs of the final assembly. Confirm compliance with relevant safety standards for the intended market before integration.

Selection Notes

Select this model for applications requiring low power isolation with a 1.5 VA capacity. It is suitable for designs needing a 115V input and split 12.6V outputs. Consider the physical dimensions and through-hole mounting style during PCB layout planning.

Part Context

This component belongs to the Triad Magnetics F-series of power transformers. These units are characterized by their compact size and reliability in general-purpose power conversion tasks. The series supports various voltage configurations to accommodate different circuit requirements.

Replacement Considerations

Direct substitutes include other 1.5 VA transformers with matching 115V primary and 2x12.6V CT secondary ratings. Verify that any replacement maintains the same 1500Vrms isolation voltage and through-hole package compatibility.
