BV201S24003A

Overview

The BV201S24003A is a single-phase encapsulated power transformer from Zettler Magnetics, designed for through-hole mounting on printed circuit boards. It features an EE20 core configuration with a rated apparent power of 0.35VA. The primary winding accepts an input voltage of 115VAC at 50/60Hz, while the secondary provides a fixed output voltage of 24VAC. The maximum secondary current rating is 14.6mA. The unit operates within a maximum ambient temperature of 70°C and utilizes a compact case dimension of 23.0x24.0mm with a height of 16.0mm.

Feature Summary

• Encapsulated construction for environmental protection
• Single-phase power conversion capability
• Through-hole mounting for PCB integration

Applications

• Low-power electronic control circuits
• Signal isolation in measurement equipment
• Component powering in consumer electronics

Procurement Notes

Verify that the specific application requires the exact 0.35VA rating and 24V secondary output. Confirm that the 115V primary input matches the available supply voltage. Ensure the through-hole footprint aligns with the PCB layout constraints. Check that the operating environment does not exceed the 70°C maximum ambient temperature limit specified for this component.

Selection Notes

Select this model when a low-voltage isolated AC source is required for small signal or control loads. The encapsulated design suits applications needing basic environmental resistance without complex cooling. Consider the physical dimensions and lead spacing to ensure compatibility with existing board space. Evaluate if the limited current capacity meets the downstream load requirements before finalizing the design.

Part Context

This component belongs to the BV Series of encapsulated power transformers by Zettler Magnetics. The series utilizes EE20 laminations to provide efficient magnetic coupling in a compact form factor. These transformers are engineered for general-purpose power conversion tasks where size and cost efficiency are prioritized over high power delivery capabilities.

Replacement Considerations

Direct substitutes include models such as BV201S18003A from the same manufacturer series. Verify that alternative part numbers match the required electrical specifications and mechanical footprint before implementation.
