BV038-5205.0

Overview

The BV038-5205.0 is a laminated core power transformer manufactured by Pulse Electronics Corporation, designed for through-hole mounting. It features a primary voltage rating of 230V and provides a secondary output of 24V at 134mA. The unit has a power capacity of 3.2VA. Physical dimensions include a width of 38.5 mm and a height of 32 mm. This component is classified under power transformers and utilizes a laminated core construction suitable for general power supply applications requiring isolated voltage conversion.

Feature Summary

• Laminated core construction for efficient magnetic flux guidance
• Through-hole mounting style for secure PCB integration
• Isolated voltage transformation from 230V primary to 24V secondary

Applications

• General purpose AC to DC power supply units
• Industrial control systems requiring isolated low-voltage DC rails
• Consumer electronics adapters utilizing standard mains input

Procurement Notes

Verify the specific datasheet for detailed insulation class, safety certifications, and thermal characteristics before finalizing design integration. Confirm that the physical footprint matches the target PCB layout, as dimensions are specified as 38.5 mm width and 32 mm height. Ensure the 3.2VA power rating meets the load requirements of the downstream circuitry to prevent saturation or overheating during operation.

Selection Notes

Select this component when a robust, cost-effective solution for stepping down standard mains voltage to a lower DC level is required. The through-hole format offers mechanical stability compared to surface-mount alternatives. Consider the 134mA secondary current limit when designing the load; ensure the application does not exceed this continuous current draw to maintain reliability and adhere to the 3.2VA power specification.

Part Context

This part belongs to the Power Transformers category within Pulse Electronics' portfolio. It serves as a fundamental building block for converting high-voltage AC inputs into usable low-voltage outputs. Unlike the SMD inductors and ferrite beads also listed in the provided data, this component performs active voltage transformation rather than signal filtering or energy storage, distinguishing its role in power management circuits.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by matching electrical ratings (230V/24V, 3.2VA) and physical dimensions (38.5mm x 32mm). Consult manufacturer catalogs for direct equivalents if sourcing constraints exist.
