DST5-28B23 is listed in the Power Transformers range at ChipApex. The manufacturer field lists Pulse Electronics. Its product description is PWR XFMR LAMINATED 12VA TH. Review the specifications below when checking this part for your BOM.
The DST5-28B23 is a laminated core power transformer manufactured by Pulse Electronics, designed for board mount applications. It features a through-hole mounting style and supports primary voltage ratings of 115 VAC and 230 VAC. The secondary output provides parallel 14V or series 28V configurations at full load, with a maximum current output capability. The unit has a maximum power rating of 12VA and weighs approximately 0.7 lb (317.51 g). It does not include a center tap and is suitable for high withstand voltage environments.
Verify the specific datasheet version to confirm electrical tolerances and thermal characteristics before integration. Ensure that the PCB footprint matches the through-hole pin configuration provided in the official mechanical drawings. Confirm that the system's input voltage aligns with the 115/230 VAC primary ratings to prevent operational failure. Check for any updated RoHS compliance documentation if required by your manufacturing standards.
Select this component when a 12VA laminated transformer is required for AC-to-DC conversion stages in energy storage or battery management systems. The ability to configure secondary outputs in parallel or series offers flexibility for different voltage rail requirements. Consider the physical dimensions and weight constraints, as the unit is relatively heavy compared to modern switching alternatives. Ensure the application environment supports the thermal profile associated with laminated core designs.
This part belongs to Pulse Electronics' power transformer lineup, specifically targeting industrial and energy storage applications. It serves as a critical isolation component in power supplies, providing galvanic separation between primary and secondary circuits. The product is actively manufactured and available for procurement, indicating stable supply chain support for ongoing production needs.
No public confirmed substitute part numbers are available in the provided documentation. Users should consult official distributor catalogs or manufacturer cross-reference guides for potential equivalents.
