Overview
The BV038-5402.0 is a laminated core power transformer manufactured by Pulse Electronics Corporation, designed for through-hole mounting. It features a 115V primary winding and a 12V secondary output. The unit provides an apparent power rating of 4VA, with the secondary capable of delivering up to 333mA. This component is RoHS compliant and lead-free, suitable for general power supply applications requiring isolated voltage conversion.
Feature Summary
- Laminated core construction for efficient magnetic flux transfer
- Through-hole termination style for secure PCB integration
- RoHS compliant and lead-free manufacturing process
Applications
- General purpose AC to DC power supplies
- Low voltage equipment requiring 12V isolation
- Industrial control systems
Procurement Notes
Verify that the specific application requires a 115V primary input and 12V secondary output configuration. Confirm that the 4VA power rating and 333mA current capacity meet the load requirements. Ensure the through-hole footprint matches the PCB design. Check for any specific regulatory compliance needs beyond standard RoHS certification.
Selection Notes
Select this transformer when a compact, low-power isolated solution is needed for 115VAC inputs. Consider the physical size constraints associated with through-hole mounting. Evaluate if the 4VA rating is sufficient for the intended circuit load. Compare against higher wattage options if increased power delivery is required.
Part Context
This component belongs to the Pulse Electronics power transformer lineup, focusing on small form-factor solutions. It utilizes traditional laminated core technology rather than modern ferrite or planar designs. The product serves as a basic isolation stage in linear or switching power architectures.
Replacement Considerations
Direct substitutes must match the 115V primary, 12V secondary, and 4VA rating. Verify pinout compatibility and mechanical dimensions before swapping. Generic replacements may differ in insulation class or thermal performance.
