DST-5-16

Overview

The Signal Transformer DST-5-16 is a Class 2 laminated core power transformer designed for through-hole mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation. The secondary configuration provides 16 V center-tapped or 8 V outputs, supporting parallel currents of 1.6 A and series currents of 800 mA. With a 12 VA power rating and 2500 Vrms isolation voltage, this component ensures superior isolation and low capacitive coupling suitable for general-purpose applications.

Feature Summary

• Provides superior electrical isolation with low capacitive coupling characteristics
• Features dual primary and dual secondary winding configurations for flexible voltage input and output
• Constructed with a laminated core design for efficient power transformation

Applications

• General purpose power supply circuits requiring Class 2 isolation
• Equipment needing 115V or 230V AC primary input conversion
• Applications utilizing 16V CT or 8V secondary power rails

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and mechanical dimensions. Confirm that the required insulation class and safety certifications align with your target market regulations. Cross-reference the terminal style and lead spacing with your PCB layout requirements before finalizing the purchase order.

Selection Notes

Select this model when a 12 VA capacity is sufficient for the load requirements. Ensure the application supports through-hole assembly techniques. Verify that the 2500 Vrms isolation rating meets the safety standards of the end equipment. Consider the physical footprint constraints as the unit requires adequate clearance for heat dissipation and mounting hardware.

Part Context

The DST-5-16 belongs to the DST series of Class 2 transformers manufactured by Bel Signal Transformer. This series is characterized by robust construction and reliable performance in standard power conversion tasks. The component serves as a fundamental building block for isolating low-voltage secondary circuits from high-voltage mains inputs in various electronic devices.

Replacement Considerations

Direct substitutes within the same series include the DST-4-16 for lower power requirements or the DST-5-20 for different voltage outputs. Always verify pin compatibility and thermal characteristics when cross-referencing alternative part numbers from the manufacturer's portfolio.
