DST-2-16

Overview

The Signal Transformer DST-2-16 is a laminated core power transformer designed for through-hole mounting. It features dual primary windings rated for 115VAC and 230VAC input, providing versatile global compatibility. The secondary configuration offers parallel 5V and series 10V outputs with maximum currents of 220mA and 110mA respectively. With a maximum power rating of 1.1VA, this Class 2 transformer ensures safety compliance. It provides 2500Vrms isolation voltage between windings. The unit measures 34.90mm in length and 28.60mm in width, with a maximum installation height of 24.60mm.

Feature Summary

• Dual primary winding design supports both 115VAC and 230VAC operation without manual switching.
• Class 2 split bobbin construction adheres to safety standards for isolated power supplies.
• Laminated core architecture delivers stable power conversion at standard frequencies.

Applications

• Low-power AC/DC power supply units
• Control circuit isolation interfaces
• Consumer electronics requiring Class 2 isolation

Procurement Notes

Verify the specific part number suffix against official datasheets to confirm pinout orientation and insulation class requirements. Ensure that the selected variant matches the required primary voltage configuration and secondary current ratings for the target application. Cross-reference manufacturer documentation for any recent packaging or component updates.

Selection Notes

Select this component when a compact, low-power transformer with dual primary flexibility is required. The 1.1VA rating suits applications with minimal load demands. Consider the physical dimensions and through-hole termination style for PCB layout constraints. Verify that the 2500Vrms isolation meets system safety regulations.

Part Context

The DST-2-16 belongs to the Split/Tran™ Class 2 Split Bobbin Transformers series by Signal Transformer. This series utilizes a split bobbin design to enhance isolation performance and safety. The product line focuses on providing reliable power transformation for small form-factor electronic devices while maintaining strict regulatory compliance.

Replacement Considerations

Direct substitutes include the ST-2-16 from the same manufacturer family, which shares similar electrical characteristics but may differ in primary voltage configuration. Always verify pin compatibility and mechanical dimensions before substitution.
