Overview
The BV048-5075.0 is a laminated core power transformer manufactured by Pulse Electronics Corporation, designed for through-hole mounting applications. It features a primary voltage rating of 115V and utilizes a parallel winding configuration for the input side. The secondary circuit provides dual output options: a parallel configuration delivering 9V at 1.11A, and a series configuration providing 18V at 555mA. This component has a total power capacity of 10VA, making it suitable for general-purpose power supply designs requiring isolated AC-to-AC conversion with specific current and voltage requirements.
Feature Summary
- Laminated core construction for efficient magnetic flux transfer
- Through-hole mounting style for robust PCB integration
- Dual secondary output configurations supporting parallel or series connections
Applications
- General purpose AC power supply units
- Industrial control systems requiring isolated power
- Consumer electronics with standard voltage requirements
Procurement Notes
Verify the specific datasheet revision to confirm electrical tolerances and pinout compatibility before integration. Ensure that the thermal management design accounts for the 10VA power dissipation characteristics under maximum load conditions. Confirm that the through-hole footprint matches the target PCB layout specifications to prevent mechanical assembly issues during manufacturing.
Selection Notes
Select this component when a 10VA isolation barrier is required between primary and secondary circuits. The choice depends on the need for either 9V/1.11A or 18V/555mA outputs based on the system's parallel or series wiring capability. Consider the physical size constraints associated with through-hole transformers compared to surface-mount alternatives for the intended enclosure design.
Part Context
This part belongs to the Power Transformers category within Pulse Electronics' portfolio. It serves as a passive electromagnetic component used to step up or step down AC voltages while providing galvanic isolation. The laminated core design distinguishes it from ferrite-based high-frequency transformers, positioning it for standard line-frequency applications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by matching primary voltage, VA rating, and secondary output configurations exactly.
