BV302D12018

Overview

The BV302D12018 is a 1.8VA encapsulated power transformer from the Zettler Magnetics BV series, designed for through-hole mounting. It features a 230V primary input and dual 12V secondary outputs, each rated at 75mA. The unit utilizes an EI30 laminated core with a case dimension of 32.8x27.8mm and a height of 24.5mm. Operating at 50/60Hz, it provides isolated power conversion suitable for compact linear power supply applications requiring reliable voltage transformation.

Feature Summary

• Fully encapsulated under vacuum pressure for enhanced efficiency and protection
• Dual secondary windings providing independent 12V outputs
• Through-hole construction for secure board integration

Applications

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

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required insulation classes and regulatory certifications. Confirm that the dual 12V secondary configuration matches the target circuit design requirements. Check RoHS3 compliance status for environmental adherence. Ensure the through-hole footprint aligns with the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when a compact, encapsulated transformer is needed for low-power applications. The 1.8VA rating suits small signal or control circuits. Consider the EI30 core size for space-constrained designs. Verify that the 230V primary input matches the available line voltage. Ensure the dual secondary output capability meets the load distribution needs of the application.

Part Context

This part belongs to the BV Series of encapsulated power transformers from Zettler Magnetics. The series is characterized by vacuum-encapsulated laminated cores designed for smaller, more efficient linear power supplies. These components are engineered to meet stringent design requirements for off-line and SMPS power sources, offering reliability in various industrial and consumer electronics environments.

Replacement Considerations

Direct substitutes include other BV series variants with matching VA ratings and pin configurations. Cross-reference datasheets for equivalent electrical parameters such as primary voltage and secondary output currents. Ensure physical dimensions and mounting style remain compatible with existing PCB footprints when considering alternative models.
