BV302D09023

Overview

The BV302D09023 is a 2.3VA encapsulated power transformer manufactured by Zettler Magnetics, designed for through-hole mounting. It features a dual primary winding configuration supporting 115V and 230V AC inputs at 50/60Hz. The secondary side provides a single 9V output with a maximum current rating of 256mA. This component utilizes an EI30 lamination size within a compact case measuring 32.8x27.8mm with a height of 29.8mm. It offers high isolation voltage capabilities suitable for various industrial applications.

Feature Summary

• Encapsulated construction for environmental protection
• Dual primary winding for universal input compatibility
• Through-hole PC pin termination style
• Compact EI30 core design

Applications

• LED lighting systems
• Electric metering devices
• Motor controls
• Thermostats

Procurement Notes

Verify the specific datasheet version to confirm insulation class and regulatory approvals such as UL or CE before integration. Ensure the PCB footprint matches the through-hole pin spacing dimensions provided in the official mechanical drawings. Confirm that the 256mA secondary current rating meets the peak load requirements of the target circuit design under all operating temperature conditions.

Selection Notes

Select this model when a compact, encapsulated transformer is required for low-power applications needing 9V DC output from standard mains voltages. The EI30 core size offers a balance between power density and physical footprint. Consider the through-hole mounting requirement against surface-mount alternatives if space constraints differ. Verify that the 2.3VA power rating sufficiently supports the connected load without exceeding thermal limits.

Part Context

This component belongs to the BV Series of encapsulated power transformers from Zettler Magnetics. The series is characterized by its suitability for LED lighting, electric metering, motor controls, and thermostats. These transformers are designed to meet stringent design requirements for off-line and SMPS power sources, providing reliable energy transfer in compact power supply circuits.

Replacement Considerations

Direct substitutes include other BV series variants with similar VA ratings and voltage configurations, such as BV302S09023, though packaging differences may exist. Cross-reference mechanical dimensions and pinout compatibility carefully. Consult the manufacturer's latest replacement guide for any updated part numbers within the EI30 form factor family.
