F-149XP

Overview

The F-149XP is a board-mount power transformer from Triad Magnetics designed for PCB integration. It features a single primary winding rated at 115 VAC and dual secondary windings providing 12.6 VCT at 0.350A, resulting in a 4.5 VA power rating. The unit utilizes through-hole termination with PC pins for secure mounting. Operating within a temperature range of 0°C to +130°C, it supports industrial control applications requiring reliable voltage transformation in compact form factors.

Feature Summary

• Dual secondary winding configuration for split-rail or center-tapped circuit requirements
• Through-hole PC pin termination for direct printed circuit board integration
• High thermal stability supporting operation up to +130°C

Applications

• Industrial control panel power supplies
• Audio equipment amplifier circuits
• Electronic test and measurement instrumentation

Procurement Notes

Verify the specific suffix designation against official Triad Magnetics documentation to confirm exact electrical tolerances and insulation class. Ensure the procurement channel provides valid RoHS compliance certificates matching the current manufacturing batch. Cross-reference the manufacturer part number with distributor catalogs to confirm availability of the correct lead style and terminal configuration before finalizing orders.

Selection Notes

Select this component when a 115VAC input must be stepped down to a 12.6VCT output with a 0.350A current capacity. The choice is appropriate for designs requiring dual isolated secondaries on a single core. Consider the physical dimensions and through-hole spacing constraints during layout. This model suits applications where high-temperature resilience and robust mechanical mounting are prioritized over surface-mount convenience.

Part Context

The F-149XP belongs to the Triad Magnetics F series of miniature impedance matching transformers. This series focuses on providing reliable power conversion in small footprints suitable for dense electronic assemblies. The component serves as a critical interface between mains voltage and low-voltage control logic or audio stages in industrial environments.

Replacement Considerations

Consult Triad Magnetics official cross-reference guides for verified substitutes. Potential alternatives include other models within the F series offering similar VA ratings and dual secondary configurations. Verify that any replacement matches the 115VAC primary specification and 12.6VCT secondary output exactly.
