Overview
The BV030-7727.0 is a laminated core power transformer manufactured by Pulse Electronics, designed for through-hole mounting. It features a primary voltage rating of 115V and a secondary output of 18V at a current capacity of 155mA. The unit has a power rating of 2.8VA. This component is classified as a general-purpose power transformer suitable for AC line applications requiring isolated voltage conversion.
Feature Summary
- Laminated core construction for efficient magnetic flux transfer
- Through-hole termination style for robust PCB integration
- Single primary to single secondary winding configuration
Applications
- AC power supply input stages
- Industrial control equipment isolation
- Consumer electronics power adapters
Procurement Notes
Verify the specific datasheet revision to confirm insulation class and safety certifications such as UL or IEC standards. Ensure the 115V primary rating matches the local mains frequency and voltage requirements. Confirm that the 155mA secondary current meets the load demands without exceeding thermal limits during continuous operation.
Selection Notes
Select this model when a low-power, isolated AC-to-AC transformation is required in a through-hole design. Compare the 2.8VA rating against total system power consumption. Consider physical dimensions and lead spacing compatibility with the target printed circuit board layout before finalizing the component choice.
Part Context
This part belongs to the BV030 series of laminated transformers from Pulse Electronics. These components are typically used in applications where cost-effective isolation and moderate power levels are sufficient. The series offers various tap configurations to suit different regional voltage standards.
Replacement Considerations
Direct substitutes include other 2.8VA laminated transformers with identical 115V primary and 18V secondary ratings. Verify pinout compatibility and mechanical footprint equivalence to ensure seamless replacement without redesigning the host circuit board.
