BV038-5413.0

Overview

The BV038-5413.0 is a laminated core power transformer manufactured by Pulse Electronics Corporation, designed for through-hole mounting on printed circuit boards. It features a primary voltage rating of 230V and a secondary output of 9V at a maximum current of 444mA. The unit has a power capacity of 4VA and provides an isolation voltage of 1.5kV. It operates within a temperature range up to +130°C.

Feature Summary

• Laminated core construction for efficient magnetic flux transfer
• Through-hole termination style for secure PCB integration
• High isolation voltage capability for safety compliance

Applications

• General purpose AC to DC power supply circuits
• Low voltage electronic device power stages
• Industrial control system auxiliary power

Procurement Notes

Verify the specific datasheet version from Pulse Electronics to confirm insulation class and regulatory approvals such as UL or CE before finalizing design integration. Ensure mechanical footprint compatibility with existing PCB layouts. Confirm that the 4VA rating meets the peak load requirements of the target application without exceeding thermal limits.

Selection Notes

Select this component when a 230V primary input and 9V secondary output are required in a compact through-hole form factor. The 4VA rating suits low-power applications where higher capacity transformers are unnecessary. Consider the +130°C operating temperature limit for high-ambient environments. Compare physical dimensions against available board space constraints.

Part Context

This transformer belongs to the BV038 series of laminated power transformers from Pulse Electronics. These components are typically used in general electronics where reliable isolation between primary and secondary windings is critical. The series offers various voltage configurations while maintaining consistent mechanical and thermal performance standards across the product line.

Replacement Considerations

The ASL150109K is a documented alternative offering similar electrical characteristics with a slightly higher 5VA rating and 555mA secondary current. Verify pinout compatibility and physical dimensions before substitution to ensure seamless integration into existing assemblies.
