BV202S12005

Overview

The BV202S12005 is a 0.5VA power transformer manufactured by Zettler Magnetics, designed for through-hole mounting. It features a single primary winding rated at 230V and a secondary winding providing 12.5V at 41.7mA. The component utilizes PC pin termination and offers an isolation voltage of 4200Vrms. Its physical dimensions are 24.00mm in length, 23.00mm in width, with a maximum seated height of 16.00mm.

Feature Summary

• Encapsulated construction for environmental protection
• Single primary to single secondary winding configuration
• Through-hole mounting with PC pin termination

Applications

• Low-power AC/DC power supply units
• Consumer electronics internal power stages
• Industrial control circuit isolation

Procurement Notes

Verify the specific manufacturer part number against official Zettler Magnetics documentation to ensure compatibility with design requirements. Confirm that the encapsulation type and thermal characteristics meet the target application's operational standards before finalizing procurement decisions.

Selection Notes

Select this model when a compact, low-power transformer is required for 230V input applications. Ensure the PCB layout accommodates the specified through-hole pitch and physical envelope. Validate that the 0.5VA rating sufficiently supports the load current demands of the downstream circuitry.

Part Context

This component belongs to the BV202 series of encapsulated power transformers from Zettler Magnetics. The series is characterized by its small footprint and reliability for general-purpose power conversion tasks. It serves as a magnetic coupling element in circuits requiring galvanic isolation between primary and secondary sides.

Replacement Considerations

Direct substitutes include other BV202 series variants such as BV202S12005 equivalents from authorized distributors. Verify that any replacement maintains identical electrical ratings, including 0.5VA power, 230V primary, 12.5V secondary, and 4200Vrms isolation.
