BV202S18003A

Overview

The BV202S18003A is a 0.35VA encapsulated power transformer manufactured by Zettler Magnetics, designed for through-hole PCB mounting. It features a single primary winding rated for 230VAC input and a single secondary winding providing an 18V output at 19.4mA maximum current. The unit utilizes an EE20 laminated core structure with dimensions of 24mm x 16mm x 23mm. This component is fully encapsulated under vacuum pressure to ensure compactness and efficiency in linear power supply applications.

Feature Summary

• Fully encapsulated construction under vacuum pressure for enhanced reliability
• Single primary to single secondary winding configuration
• Through-hole mounting design for printed circuit board integration

Applications

• Linear power supply circuits
• Low-power electronic device transformers
• Control panel power conversion

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm exact electrical parameters and mechanical tolerances. Ensure compatibility with existing PCB footprints and thermal requirements. Confirm lead times as manufacturing schedules may vary. Cross-reference datasheet specifications for insulation class and safety certifications prior to procurement.

Selection Notes

Select this component when a low-power, encapsulated transformer is required for 230VAC to 18VAC conversion. Consider the physical dimensions and through-hole mounting style for PCB layout constraints. Evaluate the 0.35VA power rating against the load requirements of the target application to ensure adequate capacity without excessive size or cost.

Part Context

This part belongs to the BV series of laminated power transformers from Zettler Magnetics. The series is characterized by vacuum-encapsulated designs intended for smaller, more efficient linear power supplies. The BV202S18003A shares common structural features with other variants in the series, differing primarily in secondary voltage and current ratings while maintaining consistent primary input and form factor.

Replacement Considerations

Direct substitutes within the same series include BV202S06003A, BV202S09003A, BV202S10003A, BV202S12003A, and BV202S15003A. These alternatives offer different secondary voltages (6V, 9V, 10V, 12V, 15V) but share identical power ratings, primary inputs, and physical dimensions. Verify that the alternative voltage matches the specific circuit requirements.
