BV302S15020

Overview

The BV302S15020 is a 2VA encapsulated power transformer manufactured by Zettler Magnetics. It features a 230VAC primary winding and a single 15V secondary output capable of delivering 133mA. Designed for through-hole PCB mounting, the unit utilizes an EI30_2 core configuration with dimensions of 32.8x27.8mm and a height of 27.4mm. The component operates within a maximum ambient temperature of 40°C and holds UL and CE certifications.

Feature Summary

• Encapsulated construction for environmental protection
• Through-hole mounting for PCB integration
• Single secondary winding configuration
• Certified compliance with safety standards

Applications

• Low-power AC-DC converter circuits
• Control panel power supplies
• Industrial instrumentation power stages
• Consumer electronics internal power isolation

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required insulation classes and regulatory approvals. Confirm that the encapsulation type matches the thermal and mechanical requirements of the target enclosure. Cross-reference the pinout diagram with the PCB layout to prevent installation errors during assembly.

Selection Notes

Select this component when a compact, low-voltage isolated power source is required for mains-operated devices. The 2VA rating suits applications with minimal current demands. Ensure the operating environment does not exceed the specified 40°C limit to maintain performance longevity and safety certification validity.

Part Context

This transformer belongs to the BV series of encapsulated power transformers from Zettler Magnetics. The series is characterized by compact EI-core designs intended for direct PCB mounting. These units provide galvanic isolation between primary and secondary circuits in space-constrained electronic assemblies.

Replacement Considerations

Consult official manufacturer substitution lists for verified equivalents. Generic replacements may differ in encapsulation material, terminal configuration, or certified safety ratings. Verify dimensional compatibility before integrating alternative components into existing footprints.
