ST-6-16

Power Transformers Overview

The ST-6-16 is a laminated core power transformer from the Signal Transformer ST series, rated at 20VA. It features a single primary winding for 115V input and dual secondary windings configured as parallel 8V at 2.5A or series 16V at 1.25A. Designed for through-hole mounting with PC pin termination, it measures 57.20mm in length, 47.60mm in width, and has a maximum seated height of 36.90mm. The unit provides 2500Vrms isolation and weighs approximately 0.8 lb (362.87 g).

Power Transformers Feature Summary

• Utilizes a split bobbin design to enhance electrical isolation capabilities.
• Offers versatile secondary output configurations via parallel or series wiring options.
• Constructed with a laminated core for standard power transformation applications.

Power Transformers Applications

• General purpose AC power supply circuits requiring isolated voltage conversion.
• Electronic equipment needing specific low-voltage secondary outputs for control logic.
• Industrial control panels utilizing standard 115V primary distribution.

Power Transformers Procurement Notes

Verify that the required secondary configuration matches the application's need for either parallel 8V or series 16V operation before procurement. Confirm that the through-hole mounting style and terminal pitch are compatible with the target PCB layout. Ensure the 20VA power rating meets the continuous load requirements of the downstream circuitry without exceeding thermal limits defined in the official datasheet.

Power Transformers Selection Notes

Select this component when a 20VA capacity is necessary for systems operating on 115V primary lines. Consider the ST-6-16 if the design requires a compact laminated core solution with split bobbin construction for improved safety isolation. Evaluate the physical dimensions against available board space, noting the specific height constraints imposed by the through-hole package and terminal arrangement.

Power Transformers Part Context

This model belongs to the ST series of Split/Tran Class 2 transformers manufactured by Signal Transformer. These components are characterized by their dual cavity platform architecture, which supports various standard configurations within the low-to-medium power range. The series is designed to meet specific regulatory standards for general-purpose power isolation in electronic assemblies.

Power Transformers Replacement Considerations

The DST-6-16 serves as a direct functional substitute within the same series, offering identical electrical specifications but potentially differing in internal construction details such as bobbin type. Verify mechanical footprint compatibility when considering alternative models from the broader ST/DST family.
