Overview
The DST-3-12 is a laminated core power transformer from the Split/Tran Class 2 series by Signal Transformer. It features dual primary windings rated for 115V and 230V AC operation at 50/60 Hz. The secondary configuration provides dual outputs: parallel connection yields 6.3V at 400mA, while series connection delivers 12.6V at 200mA. Designed for through-hole mounting with solder pins, it measures 34.90mm in length, 28.60mm in width, and has a maximum seated height of 30.80mm. The unit offers 2500Vrms isolation and weighs approximately 113.4g.
Feature Summary
- Dual primary winding design enables flexible input voltage selection between 115V and 230V AC systems.
- Split bobbin construction supports versatile secondary output configurations via parallel or series connections.
- Laminated core architecture ensures stable performance within Class 2 safety standards.
Applications
- General purpose AC to DC power supply circuits
- Industrial control panel power distribution
- Electronic equipment requiring isolated low-voltage AC sources
Procurement Notes
Verify that the specific order matches the exact part number DST-3-12 to ensure correct secondary voltage and current ratings. Confirm compliance with RoHS directives if required by your manufacturing process. Check datasheet revisions for any recent packaging or dimensional updates before finalizing procurement specifications.
Selection Notes
Select this component when a 2.4VA rating suffices for the load requirements. Ensure the PCB layout accommodates the specified through-hole pin spacing and physical dimensions. Consider the thermal characteristics of the laminated core relative to the ambient operating environment and enclosure constraints.
Part Context
This model belongs to the DST series of Split/Tran transformers, characterized by split bobbin technology for enhanced isolation and reduced electromagnetic interference. The series is designed for board-mounted applications requiring reliable performance in compact spaces with strict safety isolation requirements.
Replacement Considerations
Direct substitutes include Tamura 3FD-312 and Triad Magnetics FS12-200. Verify electrical parameters and mechanical fitment against these alternatives before implementation.
