Overview
The DST4-28B22 is a low-frequency power transformer manufactured by Pulse Electronics, designed for through-hole PCB mounting. It features a laminated core construction with a split bobbin design and horizontal plug-in orientation. The unit provides a dual secondary output configuration, delivering 28V center-tapped at 0.2A or 14V at 0.4A. Primary voltage options include 115V and 230V. The maximum seated height is 33.27mm, with overall dimensions of 41.40mm in length and 33.27mm in width.
Feature Summary
- Dual secondary winding configuration providing flexible voltage outputs
- Low-frequency open-style laminated core construction
- Horizontal plug-in mounting style for standard PCB integration
Applications
- General purpose AC to DC power supply circuits
- Industrial control system power modules
- Consumer electronics adapter applications
Procurement Notes
Verify the specific primary voltage requirement (115V or 230V) against the target application's input specifications before procurement. Confirm that the through-hole mounting footprint matches the PCB layout constraints. Ensure the physical dimensions, particularly the 33.27mm height, fit within the designated enclosure space without interference.
Selection Notes
Select this component when a dual secondary output is required from a single transformer package. The 6VA power rating suits moderate load applications. Consider the through-hole technology requirements and the specific frequency range compatibility. Verify that the laminated core type meets the thermal and efficiency needs of the design compared to alternative core materials.
Part Context
This part belongs to the DST4 series of low-frequency transformers from Pulse Electronics. The series utilizes an open-style laminated core design intended for robust performance in various power conversion environments. The specific model designation indicates the electrical characteristics and pinout configuration unique to this variant within the broader product family.
Replacement Considerations
Substitute parts must match the 6VA power rating, dual secondary voltage outputs (28V CT/0.2A or 14V/0.4A), and primary voltage options. Physical compatibility requires identical through-hole mounting dimensions and a maximum height of 33.27mm. Electrical isolation ratings and frequency response should also be verified.
