ST-6-12

Power Transformers Overview

The Signal Transformer ST-6-12 is a laminated core power transformer with a 20 VA rating. It features a single-phase primary winding rated for 115 VAC at 50/60 Hz. The secondary configuration provides dual outputs: 6.3 V parallel (3.2 A) and 12.6 V series (1.6 A). Key electrical specifications include a dielectric strength of 2500 Vrms and RoHS compliance. The unit utilizes through-hole mounting for integration into electronic circuits requiring reliable voltage conversion.

Power Transformers Feature Summary

• Laminated core construction for efficient magnetic flux transfer
• Split-bobbin design supporting multiple secondary configurations
• High dielectric isolation strength ensuring safety compliance

Power Transformers Applications

• General purpose AC to DC power supply input stages
• Industrial control panel power distribution
• Audio equipment power conditioning

Power Transformers Procurement Notes

Verify the specific secondary configuration requirements against the datasheet, as split-bobbin designs allow for various wiring options. Confirm that the 115V primary voltage aligns with the target mains supply frequency of 50 or 60 Hz. Ensure mechanical clearance accommodates the through-hole mounting style and physical dimensions specified in the official documentation before finalizing procurement orders.

Power Transformers Selection Notes

Select this model when a 20 VA capacity is required with flexible secondary voltage options. The ST-6-12 suits applications needing both low-voltage parallel and higher-voltage series outputs from a single unit. Consider the through-hole mounting constraint and verify that the 2500 Vrms isolation meets the safety standards of the end product environment compared to alternative surface-mount solutions.

Power Transformers Part Context

This component belongs to the Signal Transformer ST-6 series, which offers standard configurations for low-power applications. The series typically ranges from 1.1 VA to 36 VA, providing designers with standardized options for common voltage conversions. The ST-6-12 specifically addresses needs for 20 VA power handling with versatile secondary tap arrangements.

Power Transformers Replacement Considerations

The DST-6-12 serves as a related variant within the same series, offering dual primary voltage options (115/230 V) while maintaining similar power ratings. Verify pinout compatibility and physical footprint alignment when substituting, as primary winding configurations may differ between single and dual primary models.
