DST5-120B39

Overview

The DST5-120B39 is a split bobbin power transformer manufactured by Pulse Electronics. It features a laminated core design with a 12VA power rating. The primary winding supports 115V and 230V configurations connected in parallel, while the secondary winding provides 60V and 120V outputs configured in series or parallel. The unit delivers up to 200mA of current. This component belongs to the horizontal plug-in series designed for low-frequency applications.

Feature Summary

• Split bobbin construction for enhanced electrical isolation
• Laminated core structure optimized for low-frequency operation
• Horizontal plug-in mounting style for standard board integration

Applications

• Low-frequency power supply circuits
• Industrial equipment requiring isolated power conversion
• General purpose AC to AC voltage transformation

Procurement Notes

Verify the specific datasheet version prior to ordering to ensure alignment with current manufacturing specifications. Confirm that the primary voltage configuration matches the target application's input requirements. Check for any recent updates to the RoHS compliance status or environmental certifications. Ensure the physical dimensions of the horizontal plug-in package fit within the designated PCB footprint constraints.

Selection Notes

Select this transformer when a 12VA capacity is required for low-frequency signal or power transfer. The split bobbin architecture is suitable for applications demanding strict isolation between windings. Consider the horizontal form factor if vertical clearance is limited but board space allows for lengthwise placement. Validate that the 200mA output current meets the load demands without exceeding thermal limits.

Part Context

This component is part of Pulse Electronics' broader portfolio of audio and signal transformers as well as power transformers. The DST5 series specifically addresses needs for open-style, laminated core transformers. It serves as a specialized solution within the company's lineup for discrete power conversion tasks rather than integrated circuit solutions.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official distributor databases for cross-reference information. Verify compatibility with existing thermal management and mechanical mounting systems before considering alternative components.
