Overview
The BV020-5431.0 is a laminated core power transformer manufactured by Pulse Electronics Corporation, designed for through-hole mounting. It features a single-phase configuration with a 230V primary input voltage. The secondary side provides dual outputs: a parallel 12V winding rated at 28mA and a series 24V winding rated at 14mA. The unit has a power rating of 0.35VA and complies with RoHS standards. It adheres to UL 506 (File E113449), UL 1585 (File E175197), and EN61558 safety certifications.
Feature Summary
- Laminated core construction for efficient magnetic flux transfer
- Dual secondary output options supporting parallel or series configurations
- Through-hole mounting design for secure PCB integration
Applications
- Low-power AC/DC power supply units
- Consumer electronics requiring isolated power stages
- Industrial control systems with standard voltage inputs
Procurement Notes
Verify the specific datasheet version and certification file numbers (UL 506, UL 1585, EN61558) against current regulatory requirements before integration. Confirm that the 0.35VA power rating and 28mA/14mA current limits meet the load demands of the target circuit. Ensure through-hole footprint compatibility with the assembly process.
Selection Notes
Select this component when a compact, low-power laminated transformer is required for 230V primary applications. The dual secondary windings allow flexibility in obtaining either 12V or 24V outputs depending on the wiring configuration. Consider the thermal performance and physical size constraints associated with the 0.35VA rating in the final enclosure design.
Part Context
This part belongs to the BV020 series of power transformers from Pulse Electronics, which are characterized by their small form factor and laminated core technology. The series is intended for general-purpose power conversion tasks where space efficiency and basic isolation are prioritized over high-power delivery.
Replacement Considerations
Cross-reference with other Pulse Electronics BV020 variants such as BV020-5411.0 through BV020-5434.0 for alternative voltage or current ratings. Verify pinout compatibility and mechanical dimensions before substituting with components from other manufacturers.
