Overview
The BV038-5219.0 is a laminated core power transformer manufactured by Pulse Electronics, designed for through-hole mounting. It features a 230V primary winding configured in parallel and dual secondary windings offering 15V (parallel) and 30V (series) outputs. The component has a total power rating of 3.2VA. Secondary current capabilities are specified as 214mA for the parallel configuration and 107mA for the series configuration.
Feature Summary
- Laminated core construction for efficient magnetic coupling
- Dual secondary output options providing flexible voltage configurations
- Through-hole termination style for PCB integration
Applications
- General purpose AC to DC power supply circuits
- Low power electronic equipment requiring isolated DC rails
- Industrial control systems with standard mains input
Procurement Notes
Verify the specific datasheet version for the BV038-5219.0 to confirm exact pinout assignments and insulation class ratings before finalizing design integration. Ensure that the selected mounting orientation accommodates the physical dimensions of the laminated core assembly on the target printed circuit board layout.
Selection Notes
Select this component when a 3.2VA isolation barrier is required between a 230V primary source and low-voltage secondary loads. The availability of both parallel and series secondary taps allows designers to choose between higher current at lower voltage or lower current at higher voltage without changing the transformer part number.
Part Context
This transformer belongs to the BV038 series from Pulse Electronics, which focuses on general-purpose laminated power transformers. These components are typically utilized in applications where cost-effective isolation and standard electrical ratings are prioritized over high-frequency switching characteristics found in modern switch-mode power supplies.
Replacement Considerations
The ASL131215K from S&B Tech is documented as a cross-reference option. Verify mechanical footprint compatibility and electrical parameter alignment, particularly regarding the 5.4VA rating difference, before substituting.
