BV302D12012

Overview

The BV302D12012 is a 1.2VA encapsulated power transformer from Zettler Magnetics, designed for through-hole mounting. It features a 230V primary input and dual 12V secondary outputs, each rated at 50mA. The device operates on 50/60 Hz frequencies with an isolation voltage of 3300Vrms. Key physical dimensions include a height of 18.5mm and a width of 12.5mm. It belongs to the BV series of laminated transformers, offering vacuum-encapsulated construction for compact linear power applications.

Feature Summary

• Fully encapsulated under vacuum pressure for enhanced efficiency and compactness
• Dual secondary windings providing isolated 12V outputs
• Through-hole mounting configuration for PCB integration

Applications

• Linear power supply circuits requiring dual polarity rails
• Low-power electronic equipment with 1.2VA load requirements
• Industrial control systems utilizing standard AC mains input

Procurement Notes

Verify component authenticity by cross-referencing the part number BV302D12012 with official Zettler Magnetics documentation. Ensure the received units match the specified 1.2VA rating and dual 12V secondary configuration. Confirm that the encapsulation type and pinout align with the datasheet specifications before integration into production assemblies.

Selection Notes

Select this transformer when a compact, encapsulated solution is required for low-power dual-output applications. The 1.2VA rating suits devices with modest current demands. Consider the through-hole form factor and specific 230V primary requirement. Verify that the 3300Vrms isolation meets safety standards for the target enclosure design.

Part Context

This component belongs to the BV series of laminated power transformers manufactured by Zettler Magnetics. The series utilizes vacuum-pressure encapsulation to achieve smaller footprints and improved thermal performance compared to non-encapsulated alternatives. These transformers are engineered for reliability in standard AC-to-DC conversion stages within consumer and industrial electronics.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users must verify electrical compatibility, including VA rating, voltage ratios, and physical dimensions, if considering alternative manufacturers or series.
