Overview
The BV038-5199.0 is a laminated core power transformer manufactured by Pulse Electronics, designed for through-hole mounting on printed circuit boards. It features a single primary winding rated at 230V and a single secondary winding providing 18V output. The unit has a power rating of 3.2VA with a maximum secondary current capacity of 178mA. The component measures 28.00mm in seated height and lacks a center tap configuration.
Feature Summary
- Utilizes a laminated core construction for efficient magnetic coupling
- Designed for direct through-hole PCB integration
- Provides isolated voltage transformation from high-voltage primary to low-voltage secondary
Applications
- Battery Management Systems (BMS)
- Energy Storage Solutions (ESS)
- General power supply isolation circuits
Procurement Notes
Verify the specific part number suffix against official manufacturer documentation to ensure correct electrical ratings. Confirm that the laminated core type matches the thermal and mechanical requirements of the target assembly. Cross-reference the 230V primary and 18V secondary specifications with the system design constraints before finalizing procurement orders.
Selection Notes
Select this component when a 3.2VA isolation barrier is required between a 230V input source and an 18V load. Ensure the application supports through-hole assembly processes. Verify that the 178mA current limit meets the downstream circuit demands without requiring additional derating considerations.
Part Context
This transformer belongs to the Pulse Electronics power transformer portfolio, which supports silicon-based battery and energy storage solutions. The BV038 series provides reliable isolation for industrial and consumer applications requiring standardized voltage step-down capabilities.
Replacement Considerations
The BV038-5052.0 is a related variant within the same series but delivers 356mA at 18V. Verify if the higher current capacity of the alternative part is necessary or if the 178mA limit of the BV038-5199.0 is sufficient for the specific application.
