Overview
The BV042-5383.0 is a laminated core power transformer manufactured by Pulse Electronics Corporation. It features a 230V primary winding and a single 12V secondary output, rated for a maximum current of 417mA. The unit has a power rating of 5VA and utilizes through-hole mounting technology. This component is designed for general-purpose power conversion applications requiring isolated AC-to-AC voltage transformation.
Feature Summary
- Laminated core construction for efficient magnetic flux guidance
- Single secondary winding providing isolated 12V output
- Through-hole termination style for PCB integration
Applications
- General purpose AC power supply circuits
- Low voltage isolation stages in electronic equipment
- Control circuit power distribution
Procurement Notes
Verify the specific datasheet revision to confirm insulation class and safety certifications such as UL or CE before finalizing procurement. Ensure the 230V primary rating matches the local mains frequency and voltage standards. Confirm that the 417mA secondary current capacity meets the load requirements of the target application design.
Selection Notes
Select this component when a 5VA isolated transformer with a 230V input and 12V output is required. Consider the physical dimensions and lead spacing for PCB layout compatibility. Evaluate thermal performance under full load conditions to ensure adequate heat dissipation within the enclosure design constraints.
Part Context
This part belongs to the Pulse Electronics power transformer portfolio, specifically utilizing laminated core technology. It serves as a fundamental building block for offline power supplies where galvanic isolation between primary and secondary circuits is necessary for safety and noise reduction in low-power electronic systems.
Replacement Considerations
Cross-reference with ASL131112 for similar 5VA specifications, noting potential differences in secondary current ratings (450mA vs 417mA). Verify pinout compatibility and physical footprint before substituting to ensure mechanical fit on existing printed circuit boards.
