BV020-5426.0

Overview

The BV020-5426.0 is a laminated core power transformer manufactured by Pulse Electronics Corporation, designed for through-hole mounting on printed circuit boards. It features a primary voltage rating of 230V AC and provides a secondary output of 15V AC at full load. The unit has a low power capacity of 0.35VA, with a corresponding secondary current rating of 23mA. This component is lead-free and RoHS compliant, suitable for general-purpose low-voltage power conversion applications requiring isolated AC-to-AC transformation.

Feature Summary

• Laminated core construction for efficient magnetic flux guidance
• Through-hole termination style for robust PCB integration
• Isolated voltage conversion from 230V AC to 15V AC
• RoHS compliant and lead-free manufacturing

Applications

• Low-power control circuitry in industrial equipment
• Signal isolation in measurement instruments
• Power supply stages for small electronic devices
• General-purpose AC voltage step-down applications

Procurement Notes

Verify the specific datasheet version provided by Pulse Electronics or authorized distributors to confirm insulation class and safety certifications such as UL or IEC standards. Ensure that the 0.35VA power rating aligns with the thermal and electrical requirements of the target application. Confirm that the through-hole package dimensions match the PCB footprint design before finalizing procurement orders.

Selection Notes

Select this transformer when a compact, low-power solution is needed to step down standard mains voltage to a lower AC level. The 0.35VA rating limits its use to low-current circuits, making it unsuitable for high-power loads. Consider the physical size and through-hole mounting constraints during the mechanical design phase. Evaluate the operating frequency compatibility if the input source deviates from standard 50/60Hz mains frequencies.

Part Context

This component belongs to the family of laminated core power transformers offered by Pulse Electronics. These transformers are characterized by their simple construction and reliability in low-power environments. The BV020 series typically serves applications where cost-effectiveness and basic isolation are prioritized over high efficiency or miniaturization found in switch-mode alternatives.

Replacement Considerations

Direct substitutes must match the 230V primary, 15V secondary, and 0.35VA power rating. Verify that alternative parts maintain the same through-hole pin configuration and physical envelope to ensure board compatibility. Check for equivalent safety approvals if the original design requires specific regulatory compliance.
