BV202S15005

Overview

The BV202S15005 is a 0.5VA encapsulated power transformer manufactured by Zettler Magnetics. It features a 230V primary voltage and a single 15V secondary output, delivering a maximum current of 33.3mA. The component utilizes through-hole mounting with PC pin terminations. Physical dimensions are approximately 24mm in length, 19.5mm in width, and 23mm in height. The unit is designed for operation within a temperature range up to 70°C.

Feature Summary

• Fully encapsulated under vacuum pressure for enhanced efficiency and compactness
• Laminated core construction for reliable linear power supply performance
• Through-hole PCB mounting with standard PC pin terminations

Applications

• Linear power supply circuits
• Low-power electronic equipment requiring isolated AC-DC conversion
• Control panels and instrumentation systems

Procurement Notes

Verify the specific secondary voltage rating of 15V and current capacity of 33.3mA against circuit requirements. Confirm that the 230V primary input matches the available line voltage. Ensure the through-hole footprint and terminal spacing align with the printed circuit board layout. Check thermal ratings to ensure operation remains within the specified 70°C limit during continuous duty.

Selection Notes

Select this component when a small-form-factor, encapsulated transformer is required for low-power applications. The 0.5VA rating suits devices with minimal energy demands. Consider the physical dimensions of 24x19.5x23mm for enclosure space constraints. The vacuum-encapsulated design offers protection against environmental factors compared to non-encapsulated alternatives.

Part Context

This model belongs to the BV series of laminated power transformers from Zettler Magnetics. The series is characterized by full encapsulation under vacuum pressure, aiming for smaller size and higher efficiency in linear power supplies. The BV202S15005 represents a specific configuration within this family, defined by its 0.5VA power handling and 15V secondary output.

Replacement Considerations

Cross-reference part numbers such as BV202S12005 for similar 0.5VA transformers with different secondary voltages (e.g., 12V). Verify that any substitute maintains the same 230V primary rating, encapsulation type, and through-hole mounting style to ensure mechanical and electrical compatibility.
