BV302S09023

Overview

The BV302S09023 is a 2.3VA encapsulated power transformer manufactured by Zettler Magnetics, designed for through-hole mounting. It features a single primary winding rated for 230VAC input and a single secondary winding providing 9VAC output at full load. The device supports a maximum secondary current of 256mA and offers 4200VRMS isolation voltage between windings. Constructed with PC pin termination, it measures approximately 32.8mm in length. This component complies with RoHS3 standards and is classified under ECCN EAR99.

Feature Summary

• Encapsulated construction provides environmental protection and mechanical stability
• High isolation voltage capability ensures safety compliance in low-power applications
• Through-hole PC pin termination facilitates standard PCB assembly processes

Applications

• Low-power AC to DC converter circuits
• Industrial control system power supplies
• Consumer electronics internal power stages

Procurement Notes

Verify the specific datasheet version from Zettler Magnetics to confirm dimensional tolerances and thermal characteristics before finalizing design integration. Ensure that the 230VAC primary rating aligns with the target regional electrical standards. Confirm that the encapsulated type meets the required flammability and humidity resistance specifications for the intended operating environment.

Selection Notes

Select this component when a compact, encapsulated solution is required for 230VAC to 9VAC conversion with moderate current demands. The 2.3VA rating suits applications where space constraints preclude larger laminated transformers. Verify that the 256mA output current meets the downstream circuit requirements without exceeding the thermal limits of the encapsulation material.

Part Context

This part belongs to the BV302 series of encapsulated power transformers from Zettler Magnetics. The series typically utilizes EI core laminations enclosed in a protective resin. Similar parts in the lineup vary primarily in VA rating, secondary voltage, and physical dimensions while maintaining consistent encapsulation and isolation characteristics.

Replacement Considerations

Direct replacements must match the 2.3VA rating, 230VAC primary, 9VAC secondary, and 256mA current capacity. Verify footprint compatibility for through-hole mounting and ensure equivalent 4200VRMS isolation voltage. Cross-reference with other encapsulated transformer models from Zettler or alternative manufacturers offering identical electrical parameters.
