BV202D10005

Overview

The BV202D10005 is a 0.5VA encapsulated power transformer from Zettler Magnetics, designed for through-hole mounting. It features a 230V primary input and dual secondary outputs of 10.5V at 25mA and 10V at 30mA. The unit utilizes an EE20 lamination size with a case dimension of 23.0x24.0mm and a height of 19.5mm. This component provides efficient linear power conversion within a compact form factor suitable for various electronic applications.

Feature Summary

• Fully encapsulated under vacuum pressure for enhanced efficiency and protection
• Dual secondary windings providing independent voltage outputs
• Through-hole construction for secure printed circuit board mounting

Applications

• Linear power supply circuits requiring isolated AC voltage
• Electronic devices needing compact step-down transformation
• Control systems utilizing low-power AC components

Procurement Notes

Verify the specific secondary current ratings against your design requirements, as the datasheet indicates 25mA for the 10.5V winding and 30mA for the 10V winding. Confirm that the 230V primary rating aligns with your local mains frequency and voltage standards. Ensure the through-hole pin spacing matches your PCB layout constraints before finalizing procurement.

Selection Notes

Select this model when a small footprint and encapsulated construction are required for low-power applications. The EE20 core size offers a balance between physical dimensions and 0.5VA capacity. Consider the dual secondary configuration if separate voltage rails are needed without additional transformers. Verify thermal management needs, as encapsulation may affect heat dissipation compared to open-frame designs.

Part Context

This component belongs to the BV series of laminated power transformers by Zettler Magnetics. The series is characterized by vacuum-encapsulated construction, which contributes to smaller size and improved efficiency. These transformers are designed for general-purpose power conversion in consumer and industrial electronics where space is limited.

Replacement Considerations

Check for other BV series variants with compatible VA ratings and pin configurations. Ensure any substitute maintains the 230V primary input and similar secondary voltage levels. Verify that the replacement part supports through-hole mounting and fits within the 23.0x24.0mm case dimensions.
