BV302D09012

Overview

The BV302D09012 is a single-phase power transformer from the Zettler Magnetics BV series, designed for through-hole mounting. It features a laminated core construction with full encapsulation under vacuum pressure to ensure efficiency and compactness. The unit operates with a primary input voltage of 230 volts and provides a secondary output voltage of 9 volts at 67 mA. The power rating is specified as 1.2 VA. This component supports standard line frequencies of 50/60 Hz and utilizes an EI30/12.5 core configuration.

Feature Summary

• Fully encapsulated under vacuum pressure for enhanced efficiency and compact linear power supply design
• Laminated core construction providing reliable magnetic performance
• Single-phase configuration suitable for standard AC power conversion applications

Applications

• Linear power supply circuits requiring isolated AC voltage transformation
• Electronic equipment utilizing 9V AC secondary requirements
• Industrial control systems needing compact encapsulated transformers

Procurement Notes

Verify the specific part number suffix against official Zettler Magnetics documentation to confirm electrical characteristics and physical dimensions. Ensure compatibility with the target PCB layout for through-hole mounting. Cross-reference the 230V primary and 9V secondary ratings with system design requirements before procurement.

Selection Notes

Select this component when a compact, encapsulated power transformer is required for 230V to 9V step-down applications. Consider the 1.2 VA power rating and 67 mA current limit to ensure adequate capacity for the load. The through-hole mounting style and vacuum-encapsulated construction are key factors for mechanical stability and environmental protection in linear power designs.

Part Context

This transformer belongs to the BV series of encapsulated power transformers manufactured by Zettler Magnetics. The series is characterized by vacuum-pressure encapsulation techniques aimed at reducing size while maintaining high efficiency. These components are typically used in applications where space constraints and thermal management are critical considerations for power conversion modules.

Replacement Considerations

Consult official Zettler Magnetics substitution guides or distributor cross-reference lists for verified equivalent part numbers. Ensure any replacement matches the 230V primary, 9V secondary, 1.2 VA rating, and through-hole mounting specifications. Verify that alternative components maintain the same encapsulation type and core configuration.
