ST-2-36

Power Transformers Overview

The Signal Transformer ST-2-36 is a laminated core power transformer from the ST series, designed for through-hole mounting. It features a single primary winding rated at 115VAC and dual secondary windings providing split or center-tapped outputs of 36VCT at 0.03A (18V at 0.06A). With a maximum power rating of 1.1VA, this component operates at 50/60Hz and offers 2500Vrms isolation voltage. The unit measures 34.9mm in length, 28.6mm in width, and has a maximum seated height of 24.60mm, weighing approximately 77.11g.

Power Transformers Feature Summary

• Utilizes a split bobbin design to enhance electrical isolation between windings
• Provides dual secondary windings suitable for split or center-tapped configurations
• Constructed with a laminated core for efficient magnetic coupling
• Complies with RoHS3 standards for environmental safety

Power Transformers Applications

• Low-power AC to DC power supply circuits
• Class 2 isolated power sources
• Electronic equipment requiring 115VAC input conversion
• Control transformers for signal processing applications

Power Transformers Procurement Notes

Verify the specific secondary configuration required, as the part supports both split and center-tapped outputs. Confirm that the 1.1VA power rating meets the load requirements of the target circuit. Ensure the through-hole mounting style and physical dimensions are compatible with the printed circuit board layout. Check for RoHS3 compliance if environmental regulations apply to the final assembly.

Power Transformers Selection Notes

Select the ST-2-36 when a compact, low-power transformer is needed for 115VAC systems. The split bobbin architecture is advantageous for applications demanding high isolation reliability. Consider the 1.1VA limit when calculating total system power consumption. The through-hole package ensures mechanical stability in vibration-prone environments compared to surface-mount alternatives.

Power Transformers Part Context

This component belongs to the ST series of Split/Tran Class 2 transformers manufactured by Signal Transformer. The series is characterized by its use of split bobbins to improve insulation performance. These transformers are widely used in industrial and commercial electronics where reliable isolation and compact form factors are essential for power distribution.

Power Transformers Replacement Considerations

The DST-2-36 is a direct substitute within the same product family, offering identical electrical specifications but potentially differing in packaging or minor mechanical attributes. Verify that any replacement maintains the 1.1VA rating and 2500Vrms isolation capability.
