BV202D09003A

Overview

The BV202D09003A is a through-hole encapsulated power transformer from Zettler Magnetics. It features a laminated EE20 core with a rated power of 0.35VA. The device operates with a primary voltage of 230V and provides a single secondary output of 9V at 19.4mA. The physical case dimensions are 23.0 x 24.0 mm with a height of 16.0 mm.

Feature Summary

• Encapsulated construction for environmental protection
• Through-hole mounting configuration
• Laminated EE20 core design

Applications

• Low-power electronic circuits requiring isolated AC-DC conversion stages
• Control systems utilizing standard mains input voltages
• Compact consumer electronics housing

Procurement Notes

Verify the specific datasheet version to confirm insulation class and safety certifications such as UL or IEC standards. Ensure the operating temperature range aligns with your system requirements. Confirm that the encapsulation type meets your environmental exposure needs. Cross-reference pinout diagrams during PCB layout to prevent installation errors.

Selection Notes

Select this component when a compact, low-power transformer is needed for direct mains connection. The 0.35VA rating suits minimal load applications. The encapsulated form factor reduces assembly complexity compared to open-frame variants. Verify space constraints against the 23.0x24.0mm footprint before integration.

Part Context

This model belongs to the BV series of encapsulated power transformers by Zettler Magnetics. The series utilizes EE20 laminated cores to achieve efficient magnetic coupling in small volumes. These units are designed for general-purpose isolation in low-voltage AC applications.

Replacement Considerations

Check for equivalent models within the BV series offering identical electrical ratings but different lead configurations. Verify mechanical compatibility if panel mounting is required. Ensure substitute parts meet the same safety regulatory approvals.
