F48-023

Overview

The F48-023 is a split bobbin power transformer designed for printed circuit board mounting. It features a single primary winding rated at 115 VAC and dual secondary windings configured for series or parallel operation. The unit provides a total power rating of 1.1 VA with a rated operating frequency of 50 Hz or 60 Hz. Electrical isolation is specified at 2500 VRMS. The component utilizes six through-hole pins for termination and is constructed to meet UL recognition standards under file E53148.

Feature Summary

• Split bobbin architecture eliminates electrostatic shielding requirements by positioning primaries and secondaries side-by-side.
• Dual secondary configuration allows flexible voltage output options in either series or parallel modes.
• High insulation capability ensures safety compliance for PCB-mounted applications.

Applications

• Power supply circuits requiring compact PCB integration
• Industrial control systems utilizing Class 2 or Class 3 isolation
• Electronic equipment needing low-capacitive coupling for signal integrity

Procurement Notes

Verify the specific secondary voltage configuration required, as the base model supports multiple tap arrangements. Confirm that the 1.1 VA power rating meets the load demands of the target application. Ensure the PCB footprint matches the six-pin through-hole specification. Check for any updated UL certification status before finalizing procurement documentation.

Selection Notes

Select this component when space constraints necessitate a flat profile and low parasitic capacitance. The split bobbin design is optimal for applications sensitive to electrostatic interference. Consider the dual secondary flexibility if variable output voltages are needed from a single transformer unit. Validate thermal performance within the intended enclosure environment.

Part Context

This part belongs to Triad Magnetics' Split Pack series, which specializes in nonconcentrically wound transformers for PCB applications. The series ranges from 1.1 VA to higher power levels, offering various primary and secondary combinations. The F48-023 represents the entry-level power tier within this versatile family, emphasizing cost-effective shielding elimination.

Replacement Considerations

Direct substitutes include other split bobbin transformers from Triad such as the F12-090 or F16-070, provided they match the 1.1 VA rating and pinout. Cross-manufacturer replacements must verify identical core geometry and insulation ratings to maintain PCB layout compatibility.
