BV201D12005

Overview

The BV201D12005 is a 0.5VA encapsulated power transformer manufactured by Zettler Magnetics, designed for through-hole mounting. It features a single primary winding rated for 115V input and dual secondary windings providing 12.5V at 20.8mA and 12V at 20.8mA. The component utilizes PC pin termination and measures 24.00mm in length by 23.00mm in width. Constructed with an EE20-10 core, it offers reliable voltage transformation for low-power applications requiring compact dimensions and vacuum-pressure encapsulation.

Feature Summary

• Fully encapsulated under vacuum pressure for enhanced efficiency and compactness
• Dual secondary windings support flexible output configuration
• Through-hole mounting with PC pin termination for secure board integration

Applications

• Low-power linear power supply circuits
• Compact electronic devices requiring isolated AC-DC conversion stages
• Industrial control systems with space-constrained PCB layouts

Procurement Notes

Verify the specific secondary voltage requirements against the datasheet specifications before ordering. Confirm that the through-hole footprint matches the target PCB design. Ensure the 0.5VA power rating meets the load demands of the application to prevent overheating or performance degradation during continuous operation.

Selection Notes

Select this model when a small form factor is critical due to its 24mm x 23mm dimensions. Choose over larger transformers if the application requires only 0.5VA capacity. Consider the dual secondary outputs if multiple voltage rails are needed from a single transformer unit without additional components.

Part Context

This component belongs to the BV series of laminated power transformers from Zettler Magnetics. The series is characterized by vacuum-pressure encapsulation techniques aimed at reducing size while maintaining electrical performance. It serves as a standard solution for general-purpose power isolation in consumer and industrial electronics where moderate reliability and cost-effectiveness are prioritized.

Replacement Considerations

Check for direct substitutes within the BV series that match the 0.5VA rating and similar physical dimensions. Verify compatibility of the EE20-10 core type and pin spacing if replacing with other manufacturers' equivalents. Ensure the replacement part maintains the same encapsulation standards for environmental protection.
