BV038-5190.0

Overview

The BV038-5190.0 is a laminated core power transformer manufactured by Pulse Electronics, designed for through-hole mounting. It features a primary voltage rating of 230V and a secondary output of 9V at 356mA, delivering a total power capacity of 3.2VA. The component operates within a standard temperature range and complies with RoHS3 specifications. Its physical dimensions include a maximum seated height of 28.00mm, with an overall footprint measuring 42.00mm in length and 35.50mm in width. This configuration supports reliable electrical isolation and efficient power conversion for general-purpose applications requiring specific voltage step-down capabilities.

Feature Summary

• Laminated core construction for stable magnetic performance
• Through-hole termination style for robust PCB integration
• Single secondary winding providing 9V output
• RoHS3 compliant manufacturing process

Applications

• General purpose AC to DC power supply units
• Industrial control system power modules
• Consumer electronics requiring isolated low-voltage DC sources

Procurement Notes

Verify the specific datasheet version corresponding to the 230V primary and 9V secondary configuration before procurement. Confirm that the through-hole pin spacing matches the target PCB layout, as dimensions are fixed at 42.00mm x 35.50mm. Ensure thermal management strategies account for the 3.2VA power dissipation during continuous operation. Cross-reference the manufacturer part number strictly to avoid confusion with similar series variants having different voltage ratings or core types.

Selection Notes

Select this transformer when a dedicated 230V to 9V isolation stage is required with a current capacity up to 356mA. Consider the physical size constraints due to the 28.00mm height and large footprint relative to surface-mount alternatives. Evaluate if the laminated core efficiency meets the specific thermal requirements of the enclosure. Compare against other Pulse Electronics transformers if higher power density or different voltage ratios are needed for the application design.

Part Context

This component belongs to Pulse Electronics' line of laminated core power transformers, which are distinct from their switching mode power supplies or signal transformers. The BV038 series typically utilizes traditional iron-lamination technology for linear power applications. These components serve as fundamental building blocks for creating isolated DC voltages from mains AC input, differing significantly from high-frequency switch-mode counterparts in terms of weight, size, and operational frequency characteristics.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing PCB footprints and thermal profiles before considering alternative manufacturers. Check for equivalent VA ratings and voltage configurations in competitor catalogs if direct substitution is necessary.
