BV302S12020

Overview

The BV302S12020 is a 2VA power transformer from the Zettler Magnetics BV Series, designed for through-hole mounting. It features an EI30/15.5 laminated core with encapsulated construction. The primary winding accepts 230VAC input, while the secondary provides a 12VDC output at 167mA. Physical dimensions are 32.8mm x 27.8mm with a height of 27.4mm.

Feature Summary

• Encapsulated laminated core construction for environmental protection
• Radial lead configuration for standard through-hole PCB assembly
• EI30/15.5 core geometry optimized for compact power applications

Applications

• Low-power AC to DC conversion circuits
• Control panel power supplies
• Industrial instrumentation isolation

Procurement Notes

Verify the specific datasheet revision and insulation class requirements against your design specifications. Confirm that the radial lead spacing matches your PCB footprint exactly. Ensure the encapsulation type meets any relevant safety or environmental standards required for your final product deployment.

Selection Notes

Select this component when a 2VA capacity is sufficient for the load. The 230V primary rating suits regions with standard mains voltage. Consider the physical envelope size constraints, as the encapsulated package adds volume compared to open-frame transformers. Verify thermal management needs based on the 2VA dissipation.

Part Context

This part belongs to the BV Series of encapsulated power transformers by Zettler Magnetics. These units typically utilize EI laminations and are designed for general-purpose isolation in low-voltage AC applications. The series offers various voltage combinations within similar physical footprints.

Replacement Considerations

Check for direct substitutes with identical VA ratings, primary/secondary voltages, and lead configurations. Ensure replacement parts maintain the same EI30 core size and encapsulation style to fit existing mechanical constraints.
