BV201S09005

Overview

The BV201S09005 is a 0.5VA power transformer manufactured by Zettler Magnetics, designed for through-hole mounting. It features a single primary winding rated for 115V input and a single secondary winding providing 9.5V at full load. The maximum peak output current is 55.6mA. The component utilizes an EE20-10 laminated core structure with encapsulated construction. Physical dimensions are 24.00mm in length and 23.00mm in width, with a maximum height of 19.5mm. It operates within a temperature range up to 70°C and complies with RoHS3 standards.

Feature Summary

• Encapsulated construction for environmental protection
• Single primary and secondary winding configuration
• Through-hole PC pin termination style
• EE20-10 laminated core design

Applications

• Low-power AC-DC power supply circuits
• Control transformer applications in consumer electronics
• Signal isolation in low-voltage systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct voltage and current ratings. Confirm that the encapsulated type matches the thermal and mechanical requirements of the target assembly. Check for compliance with regional environmental regulations such as RoHS3 before finalizing procurement orders.

Selection Notes

Select this component when a compact, low-power transformer is required for 115V primary applications. Ensure the PCB layout accommodates the through-hole footprint and the physical envelope of 24.00mm x 23.00mm. Verify that the 55.6mA output current meets the load requirements of the downstream circuitry without exceeding thermal limits.

Part Context

This part belongs to the EE20 series of power transformers from Zettler Magnetics. It is distinct from higher-capacity models like the AHI series due to its lower 0.5VA rating and smaller EE20 core size. The encapsulated design differentiates it from open-frame variants, offering better durability for general-purpose electronic assemblies.

Replacement Considerations

Direct substitutes must match the 0.5VA rating, 115V primary, 9.5V secondary, and through-hole package. Verify core type (EE20) and encapsulation status. Cross-reference with other manufacturers' equivalent low-power encapsulated transformers ensuring identical electrical parameters and mounting dimensions.
