F28-1300

Overview

The Triad Magnetics F28-1300 is a laminated core power transformer designed for board mount applications. It features a single primary winding rated for 115V input and dual secondary windings providing a center-tapped output of 28.0Vct at 1.3A. The unit has a power rating of 36 VA and utilizes through-hole solder pin termination. Physical dimensions are 2.63 inches in length, 2.19 inches in width, and 1.56 inches in height. It carries UL/cUL certification for Class 2/3 compliance.

Feature Summary

• Dual secondary winding configuration with center tap capability
• Split bobbin design for versatile PC board integration
• Single primary winding optimized for 115V operation
• Through-hole mounting style with solder pin termination

Applications

• Audio amplifier power supplies
• Industrial control systems
• Consumer electronics power regulation

Procurement Notes

Verify the specific suffix requirements for your application, as variants like F28-1300-C2 exist with split pack configurations. Confirm that the 115V primary voltage matches your local mains supply or requires an autotransformer. Ensure PCB layout accommodates the specified physical footprint and through-hole spacing. Check for updated UL/cUL safety certifications relevant to your target market before finalizing procurement.

Selection Notes

Select this component when a 36 VA power rating and 28Vct output are required for 115V systems. Compare against the VPP series if lower power ratings or different form factors are needed. Consider the F28-1300-C2 variant if a split bobbin structure is necessary for enhanced isolation or specific mounting constraints. Evaluate thermal management requirements based on the 1.3A continuous current rating.

Part Context

This part belongs to the Triad Magnetics F28 series of power transformers. The series offers various voltage and current combinations while maintaining consistent mounting styles. It is distinct from the WSU series, which provides wall-mounted AC adapters rather than board-mount components. The F28 series is engineered for reliable performance in general-purpose power conversion tasks.

Replacement Considerations

The F28-1300-C2 is a related variant within the same family, offering a split pack configuration. Direct replacements must match the 36 VA rating, 28Vct output, and 115V primary specification. Verify that substitute parts maintain the same physical dimensions and pinout compatibility for seamless integration.
