3FS-524

Power Transformers Overview

The Tamura 3FS-524 is a laminated core power transformer designed for through-hole mounting. It features a single primary winding rated at 115V and dual secondary windings supporting parallel 12V (1A) or series 24V (0.5A) configurations. The unit provides a maximum power rating of 12VA with a 2500Vrms isolation voltage. Physical dimensions are 48.50mm in length, 41.52mm in width, and up to 38.00mm in height. It utilizes PC pin termination and is RoHS compliant.

Power Transformers Feature Summary

• Laminated magnetic core construction for efficient power transfer
• Dual secondary winding capability allowing flexible parallel or series voltage output
• High isolation voltage rating for enhanced safety
• Through-hole mounting style with PC pin termination

Power Transformers Applications

• General purpose AC to DC power supply circuits
• Industrial control panel power distribution
• Consumer electronics internal power conversion
• Signal processing equipment power stages

Power Transformers Procurement Notes

Verify the specific datasheet revision prior to ordering, as manufacturing locations may vary across multiple devices. Confirm that the required insulation class and thermal performance meet the target application's environmental constraints. Ensure the through-hole footprint matches the PCB design specifications exactly. Check for any recent product change notifications regarding material composition or regulatory compliance updates.

Power Transformers Selection Notes

Select this component when a 12VA power rating is sufficient and dual secondary outputs are required. The 115V primary input limits suitability for regions requiring 230V direct connection without additional configuration. Consider the physical size constraints due to the 48.50mm length. Verify that the 2500Vrms isolation meets safety standards for the intended electrical environment.

Power Transformers Part Context

This part belongs to the Tamura 3FS-5xx series of three-flange power transformers. These components are engineered for board-mounted applications requiring reliable isolation between primary and secondary circuits. The series offers various voltage combinations to accommodate different global input standards and output requirements within a standardized mechanical envelope.

Power Transformers Replacement Considerations

Direct substitutes include ST-5-24 from Signal Transformer and F24-500 from Triad Magnetics. Verify that alternative parts match the 12VA rating, 115V primary input, and dual secondary output capabilities. Ensure mechanical dimensions and pinout compatibility before integration.
