3FD-248

Power Transformers Overview

The Tamura 3FD-248 is a laminated core power transformer designed for through-hole mounting. It features dual primary windings rated for 115 VAC and 230 VAC, and dual secondary windings providing 24V outputs that can be configured in series for 48V. The unit has a power rating of 1.1 VA and a maximum output current of 23 mA. Physical dimensions include a length of 35.56 mm, width of 31.00 mm, and height of 38 mm. Termination is via PC pins.

Power Transformers Feature Summary

• Dual primary winding configuration supporting 115 VAC and 230 VAC input voltages
• Dual secondary windings allowing parallel or series connection for flexible voltage output
• Laminated core construction optimized for standard power frequency applications

Power Transformers Applications

• General purpose AC to DC power supply circuits
• Industrial control panel power distribution
• Consumer electronic device internal power isolation

Power Transformers Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status and lead times, as manufacturing updates may occur. Confirm that the required secondary voltage configuration (series vs. parallel) matches the circuit design before ordering. Ensure PCB footprint compatibility with the specified PC pin spacing and board thickness constraints.

Power Transformers Selection Notes

Select this component when a compact 1.1 VA isolation transformer is required for low-power applications. The dual secondary design offers flexibility for 24V or 48V systems. Consider thermal dissipation limits given the small form factor and ensure adequate ventilation in enclosed assemblies to maintain safe operating temperatures under full load conditions.

Power Transformers Part Context

The 3FD series represents Tamura's line of general-purpose laminated power transformers. These components are engineered for reliability in standard industrial and commercial environments. The 3FD-248 specifically targets applications requiring moderate isolation levels with minimal footprint, serving as a foundational element in basic power conversion stages.

Power Transformers Replacement Considerations

No direct substitute part numbers are publicly confirmed for this specific model. Cross-referencing requires matching electrical ratings, physical dimensions, and pin configurations precisely.
