BV020-5424.0

Overview

The BV020-5424.0 is a laminated core power transformer manufactured by Pulse Electronics, designed for chassis mounting applications. It features a single primary winding rated at 230V and a single secondary winding providing 9V output with a maximum current capacity of 39mA. The unit has a low power rating of 0.35VA and utilizes a through-hole termination style for PCB integration. The physical dimensions are specified as 22.00mm in length, 23.00mm in width, and a maximum height of 15.00mm. The component weighs approximately 34.93 grams and employs an EE20/6.1 core type configuration.

Feature Summary

• Laminated core construction for efficient magnetic flux guidance
• Single primary to single secondary isolation topology
• Chassis or panel mount installation capability
• Through-hole termination for robust mechanical connection

Applications

• Low-power AC to DC conversion stages
• Industrial control panel power supplies
• Instrumentation equipment internal power distribution
• Consumer electronics auxiliary power circuits

Procurement Notes

Verify the specific voltage and current requirements against the design specifications before procurement. Confirm that the chassis mounting footprint matches the available space in the target enclosure. Ensure the operating frequency aligns with the transformer's design parameters. Check for any regional compliance certifications required for the final assembly. Validate the thermal management strategy given the 0.35VA power dissipation.

Selection Notes

Select this component when a compact, isolated power source is needed for low-current applications. Consider the physical size constraints due to the 22x23mm footprint. Evaluate the need for chassis mounting versus board-only solutions. Compare alternative transformers if higher current or different voltage ratios are required. Assess the impact of the through-hole technology on the manufacturing process.

Part Context

This transformer belongs to the broader category of laminated core power transformers used in general-purpose electronic equipment. It serves as a fundamental building block for stepping down mains voltage to safer, usable levels for sensitive circuitry. Similar components in this class typically offer reliable isolation and moderate power handling capabilities suitable for non-critical power rails.

Replacement Considerations

Direct substitutes include models with identical electrical ratings such as the BV020-5423.0 (6V output) or BV020-5428.0 (24V output), provided the voltage difference is acceptable. Verify that any replacement maintains the same 0.35VA power rating and physical dimensions to ensure compatibility with existing mounting structures.
