DST-4-10

Overview

The Signal Transformer DST-4-10 is a laminated core power transformer rated at 6VA, designed for through-hole mounting. It features dual primary windings supporting 115V and 230V inputs at 50/60Hz. The secondary configuration provides parallel 5V at 1.2A and series 10V at 600mA. Physical dimensions are 41.30mm length, 33.30mm width, and 33.30mm maximum height. It offers 2500Vrms isolation voltage and weighs approximately 199.58g.

Feature Summary

• Dual primary winding capability for flexible 115V or 230V input selection
• Split bobbin construction enabling independent parallel and series secondary outputs
• Laminated core design optimized for standard 50Hz and 60Hz line frequencies

Applications

• Class 2 power supply circuits requiring isolated low-voltage DC rails
• Industrial control systems utilizing split secondary configurations
• Equipment needing 2500Vrms dielectric isolation between primary and secondary

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status and REACH registration details. Ensure the ordering suffix matches the required lead time specifications, as standard delivery periods may vary by region. Confirm that the through-hole pin spacing aligns with the target PCB footprint before finalizing procurement orders.

Selection Notes

Select this component when a 6VA rating suffices for the load requirements. The dual secondary arrangement allows simultaneous generation of 5V and 10V rails from a single unit. Verify that the 2500Vrms isolation rating meets safety standards for the intended application environment. Consider the physical envelope size constraints during mechanical integration planning.

Part Context

This model belongs to the Split/Tran Class 2 transformer series manufactured by Signal Transformer. The series utilizes split bobbin technology to provide versatile secondary output configurations. These transformers are engineered for board-mount applications in industrial and commercial electronics where compact isolation is required.

Replacement Considerations

Consult official manufacturer documentation for direct cross-reference part numbers. Verify that any substitute maintains identical electrical ratings, including 6VA power, 2500Vrms isolation, and compatible physical dimensions for PCB mounting compatibility.
