DST-3-36

Power Transformers Overview

The DST-3-36 is a laminated core power transformer from the DST series, rated at 2.4 VA. It features dual primary windings for 115 VAC and 230 VAC operation at 50/60 Hz. The secondary provides 36 VCT or 18 V with current ratings of 65 mA and 130 mA respectively. Designed for through-hole mounting on printed circuit boards, it measures 34.9 mm in length, 28.6 mm in width, and 30.8 mm in height. The unit weighs approximately 110 g and utilizes solder pin termination.

Power Transformers Feature Summary

• Dual primary winding configuration supports both 115 VAC and 230 VAC input voltages.
• Center-tapped secondary output enables flexible voltage selection between 18 V and 36 V.
• Rigid pin construction ensures easier board insertion and higher mechanical reliability.

Power Transformers Applications

• Class 2 power supply circuits
• Low-power electronic equipment requiring isolated AC sources
• Control transformers for industrial panels

Power Transformers Procurement Notes

Verify the specific datasheet revision to confirm RoHS compliance status and exact physical dimensions. Ensure the selected variant matches the required secondary current rating of 65 mA or 130 mA. Confirm that the through-hole package style aligns with the target PCB footprint design before finalizing procurement orders.

Power Transformers Selection Notes

Select this component when a 2.4 VA isolation transformer is needed for 50/60 Hz applications. The dual primary winding allows compatibility with global mains voltages without rewiring. The center-tapped secondary is suitable for full-wave rectification circuits requiring split voltage rails.

Power Transformers Part Context

This part belongs to the DST series of single-phase laminated transformers manufactured by Signal Transformer. The series covers power ratings from 1.1 VA to 36 VA. These components are designed for general-purpose power transformation in compact electronic assemblies requiring reliable electrical isolation.

Power Transformers Replacement Considerations

Direct substitutes within the same series include DST-3-12 (12.6 V CT) and DST-3-20 (20 V CT). Verify that the replacement maintains the 2.4 VA power rating and compatible physical dimensions for the existing enclosure space.
