BV020-5430.0

Overview

The BV020-5430.0 is a laminated core power transformer manufactured by Pulse Electronics Corporation, designed for through-hole mounting. It features a primary voltage of 230V and operates at frequencies of 50/60Hz. The unit provides multiple secondary outputs: two parallel windings delivering 9V at 38mA, and two series windings providing 18V and 19V respectively. With a power rating of 0.35VA, the transformer utilizes a split-bobbin construction and is vacuum potted. It is classified under temperature class Ta 70°C/B and includes short-circuit protection where noted in agency approvals.

Feature Summary

• Laminated core construction with split-bobbin design
• Vacuum potting for environmental stability
• Multiple secondary output configurations including parallel and series options
• Short-circuit proof capability under specific agency approvals

Applications

• Commercial equipment requiring low power isolation
• Industrial control systems utilizing 50/60Hz mains input
• General purpose power supply units needing multiple voltage rails

Procurement Notes

Verify component status carefully as this part is listed as obsolete in major distributor databases. Confirm availability with authorized suppliers or check for valid replacement alternatives before ordering. Ensure that the required secondary current ratings (38mA) align with system design requirements. Validate that the through-hole package fits the target PCB layout constraints.

Selection Notes

Select this transformer when a compact 0.35VA isolated power source is needed for commercial applications. The specific combination of 9V parallel and 18V/19V series secondaries suits circuits requiring distinct voltage levels from a single 230V primary. Consider the 70°C temperature class and short-circuit protection features for safety-critical designs. Ensure compatibility with standard through-hole assembly processes.

Part Context

The BV020 series represents Pulse Electronics' line of laminated power transformers intended for general-purpose isolation. These components are characterized by their robust vacuum-potted construction and compliance with various agency approvals. The BV020-5430.0 specifically addresses needs for low-power, multi-tap secondary outputs in space-constrained commercial environments.

Replacement Considerations

This component is marked as obsolete. Consult manufacturer documentation for direct replacements or equivalent parts from other manufacturers offering similar 0.35VA laminated transformers with compatible pinouts and electrical characteristics.
