BV038-5414.0

Overview

The BV038-5414.0 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 12V at 333mA. The unit has a power capacity of 4VA. This component provides electrical isolation between circuits while stepping down voltage levels for downstream electronic applications.

Feature Summary

• Laminated core construction for efficient magnetic flux transfer
• Through-hole mounting configuration for PCB integration
• Electrical isolation capability between primary and secondary windings

Applications

• General purpose AC to DC power supply stages
• Low power electronic circuit isolation
• Consumer electronics power input stages

Procurement Notes

Verify the specific datasheet revision and manufacturer documentation before procurement. Confirm that the 230V primary rating aligns with your local mains frequency and voltage standards. Ensure mechanical dimensions fit the target PCB layout. Check for any obsolete status or lifecycle notices from Pulse Electronics to avoid supply chain disruptions during production.

Selection Notes

Select this component when a 4VA isolated power source is required for low-current applications. The 12V secondary output suits logic circuits or small signal processing stages. Consider the through-hole form factor if surface space is limited or higher mechanical stability is needed. Evaluate thermal performance under continuous load conditions to ensure reliability within the operating temperature range specified in the official documentation.

Part Context

This part belongs to the BV038 series of laminated power transformers from Pulse Electronics. The series offers various voltage configurations and power ratings tailored for different isolation requirements. These components are commonly used in industrial and commercial equipment where reliable galvanic isolation is critical for safety and noise reduction.

Replacement Considerations

Direct substitutes include BV038-5415.0 and similar series variants with matching 4VA ratings and through-hole packages. Verify pinout compatibility and insulation class before substitution. Cross-reference technical specifications to ensure equivalent isolation voltage and thermal characteristics.
