DST-5-10

Overview

The DST-5-10 is a laminated core power transformer from the Split/Tran series, designed for board mount applications. It features dual primary windings rated for 115 VAC and 230 VAC input, supporting 50 Hz and 60 Hz operating frequencies. The unit provides a secondary output of parallel 5V and series 10V with a 12 VA power rating. Secondary current capabilities are specified at 1.2A for the parallel configuration and 600mA for the series configuration. It utilizes through-hole PC pin termination and offers 2500Vrms isolation voltage.

Feature Summary

• Dual primary winding design enables flexible operation across 115 VAC and 230 VAC input standards.
• Split secondary architecture provides independent parallel and series voltage outputs for versatile circuit integration.
• Laminated core construction ensures efficient magnetic coupling within a compact printed circuit board mount form factor.

Applications

• General purpose AC to DC power supply circuits
• Industrial control panel power distribution
• Consumer electronics internal power regulation

Procurement Notes

Verify the manufacturer designation carefully, as sources attribute this part to both Signal Transformer and Bel Signal Transformer due to corporate acquisitions. Confirm RoHS compliance status and specific datasheet revisions prior to ordering. Ensure the procurement channel provides official documentation matching the 12 VA rating and 2500Vrms isolation specifications to avoid counterfeit or obsolete inventory risks.

Selection Notes

Select this component when a single transformer must provide two distinct secondary voltage levels from one primary source. The dual primary winding allows direct compatibility with global mains voltages without manual reconfiguration. Consider the physical dimensions and through-hole mounting requirements against available PCB real estate and mechanical constraints.

Part Context

This model belongs to the DST series of Split/Tran transformers, characterized by split bobbin construction. This design minimizes inter-winding capacitance compared to standard laminated cores, enhancing noise immunity in sensitive analog or digital switching applications. The series is engineered for reliable performance in Class 2 isolated power systems.

Replacement Considerations

DST-4-10: Offers similar electrical topology but with a lower 6 VA power rating and different secondary current limits. Verify that the reduced thermal capacity meets the application's continuous load requirements before substituting.
