Overview
The BV030-7139.0 is a laminated core power transformer manufactured by Pulse Electronics, designed for through-hole mounting. It features a primary voltage rating of 230V and provides dual secondary outputs of 12V each. The transformer delivers a total power capacity of 1.5VA with a maximum secondary current of 125mA per winding. It operates within a temperature range up to +70°C and has a physical height of 20mm.
Feature Summary
- Laminated core construction for efficient magnetic coupling
- Dual isolated secondary windings providing independent 12V outputs
- Through-hole technology compatible for standard PCB assembly
Applications
- Low-power AC/DC conversion circuits
- Isolated power supply stages in consumer electronics
- Control circuitry requiring galvanic isolation
Procurement Notes
Verify the specific secondary configuration matches system requirements, as dual 12V outputs are specified. Confirm thermal management capabilities align with the +70°C maximum operating temperature limit. Ensure mechanical clearance accommodates the 20mm height dimension during PCB layout and enclosure design phases.
Selection Notes
Select this component when dual isolated 12V rails are required from a 230V primary source. Consider the 1.5VA power limit for load calculations. Evaluate space constraints against the through-hole footprint and vertical profile. Compare against shielded alternatives if electromagnetic interference mitigation is critical for the application environment.
Part Context
This part belongs to the BV030 series of power transformers from Pulse Electronics. The series typically includes various voltage configurations and power ratings tailored for general-purpose isolation needs. The BV030-7139.0 specifically addresses applications requiring dual secondary outputs from a high-voltage primary input.
Replacement Considerations
Cross-reference with other Pulse BV030 variants or equivalent laminated core transformers offering 230V primary and dual 12V secondaries. Verify that substitute parts match the 1.5VA power rating, 125mA current limit, and physical dimensions to ensure compatibility.
