BV042-5052.0

Power Transformers Overview

The BV042-5052.0 is a laminated core power transformer manufactured by Pulse Electronics, designed for through-hole mounting. It features a single primary winding rated at 115V and a single secondary winding providing 9V at full load. The maximum output current is 556mA, with a maximum power rating of 5VA. The component has no center tap and utilizes PC pin termination. Its physical dimensions are optimized for standard PCB integration, with a maximum seated height of 28.00mm.

Power Transformers Feature Summary

• Laminated core construction for efficient magnetic coupling
• Single primary to single secondary winding configuration
• Through-hole installation with PC pin termination

Power Transformers Applications

• General purpose AC to DC power supply circuits
• Low voltage isolation in consumer electronics
• Control circuit power distribution

Power Transformers Procurement Notes

Verify the specific datasheet revision and electrical tolerances against the design requirements before procurement. Confirm that the 115V primary rating matches the local mains voltage standards. Ensure the PCB footprint accommodates the through-hole pins and the 28.00mm maximum height clearance. Check for any RoHS compliance documentation if required by regulatory standards.

Power Transformers Selection Notes

Select this transformer when a compact, low-power isolation solution is needed for 115V input applications. The 5VA rating suits light loads such as control logic or small signal processing. Consider the through-hole form factor for mechanical stability in high-vibration environments. Compare thermal performance and efficiency requirements against alternative SMD transformers if space constraints differ.

Power Transformers Part Context

This component belongs to the BV042 series of power transformers from Pulse Electronics. It is part of a family of laminated core transformers designed for general-purpose power conversion. Similar models in the series may vary in secondary voltage or current ratings while maintaining the same physical footprint and mounting style.

Power Transformers Replacement Considerations

Direct substitutes include other 5VA laminated transformers with identical 115V primary and 9V secondary specifications. Verify pin compatibility and dimensional overlap before substitution. Alternative models from the same manufacturer with different voltage taps require circuit redesign.
