BV201D24005

Overview

The BV201D24005 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 24V output at a maximum current of 10.4mA. The component utilizes an EE20 laminated core structure with dimensions of 23.0mm x 24.0mm and a height of 19.5mm. This unit serves as a linear step-down transformer for converting AC input voltages to lower power-level outputs.

Feature Summary

• Provides electrical isolation and voltage transformation from 115VAC primary to 24VAC secondary
• Utilizes an EE20 laminated core design for efficient magnetic coupling
• Supports standard through-hole PCB installation via PC pin termination

Applications

• Linear power supply circuits requiring low-power AC voltage reduction
• Control systems utilizing Class 2 or general-purpose isolated power sources
• Electronic devices operating within VDE and CE approved safety standards

Procurement Notes

Verify the specific datasheet version to confirm regulatory approvals such as UL Class 2/3, VDE, and CE, as these may vary by production batch. Ensure the application environment supports the thermal characteristics of a 0.5VA laminated transformer. Confirm that the 115V primary rating aligns with the local mains voltage requirements before integration into the final assembly.

Selection Notes

Select this model when a compact, low-power solution is required for stepping down 115VAC to 24VAC. The EE20 form factor offers a balance between size and performance for applications needing approximately 0.5VA. Consider the through-hole mounting style if mechanical stability is prioritized over surface area constraints on the PCB layout.

Part Context

This component belongs to the Zettler Magnetics power transformer portfolio, which includes various linear step-down options. The BV series typically addresses general-purpose and safety-isolated applications. The EE20 core size indicates a small footprint suitable for consumer electronics or industrial control modules where space efficiency is critical alongside basic isolation requirements.

Replacement Considerations

Direct substitutes must match the 0.5VA rating, 115V:24V turns ratio, and EE20 package dimensions. Verify that any replacement maintains equivalent insulation class and regulatory certifications (UL/VDE/CE) for the target market.
