3FD-356

Power Transformers Overview

The Tamura 3FD-356 is a board-mount power transformer with a 2.4 VA rating. It features dual primary windings rated for 115 VAC and 230 VAC operation. The secondary configuration provides dual outputs of 28 VAC at 90 mA and 56 VAC at 45 mA. Designed for through-hole installation, it utilizes a laminated core construction.

Power Transformers Feature Summary

• Dual primary winding capability for flexible voltage input selection
• Dual secondary winding architecture providing multiple output voltages
• Laminated core design for standard power transformation applications

Power Transformers Applications

• General purpose AC to DC power supply circuits
• Industrial control system power distribution
• Electronic equipment requiring isolated low-voltage DC rails

Power Transformers Procurement Notes

Verify the specific datasheet version against your design requirements. Confirm that the physical dimensions and pinout match your PCB footprint exactly. Ensure the thermal management strategy accommodates the 2.4 VA load. Check regulatory compliance documentation for your target market before finalizing procurement.

Power Transformers Selection Notes

Select this component when a 2.4 VA isolation barrier is required with specific 28 VAC and 56 VAC secondary outputs. The dual primary winding allows compatibility with both 115 VAC and 230 VAC mains inputs without rewiring. Consider the through-hole mounting style if surface mount alternatives are unsuitable for your assembly process.

Power Transformers Part Context

This component belongs to the Tamura 3FD series of power transformers. The series offers various power ratings and winding configurations for different application needs. The 3FD-356 specifically addresses requirements for moderate power isolation with dual secondary outputs in a through-hole package format.

Power Transformers Replacement Considerations

Direct substitutes within the same series include models like the 3FD-310, though secondary specifications differ. Verify electrical parameters and physical dimensions before substituting any alternative part number.
