BV202D09006

Overview

The BV202D09006 is a laminated power transformer from the Zettler Magnetics BV series, designed for through-hole mounting. It features a 230V primary input and provides a single 9V secondary output with a current rating of 33.3mA. The unit has a rated power capacity of 0.6VA and utilizes an EE20 core configuration. Physical dimensions include a case size of 23.0x24.0mm and a maximum height of 19.5mm. The transformer is fully encapsulated under vacuum pressure to ensure efficiency and compactness.

Feature Summary

• Fully encapsulated construction under vacuum pressure for enhanced efficiency
• Laminated core design utilizing EE20 geometry
• Through-hole mounting style for PCB integration

Applications

• Linear power supply circuits requiring isolated AC voltage transformation
• Low-power electronic devices needing 9V AC output
• Industrial control systems utilizing standard 230V mains input

Procurement Notes

Verify the specific secondary voltage and current requirements against the 9V/33.3mA specification before procurement. Confirm that the through-hole footprint matches the PCB layout constraints defined by the 23.0x24.0mm case dimensions. Ensure the operating temperature range aligns with the T70B classification found in official documentation. Cross-reference the part number suffix to guarantee compatibility with existing assembly processes.

Selection Notes

Select this component when a compact, encapsulated transformer is required for low-power applications. The 0.6VA rating suits devices with minimal energy demands. Consider the EE20 core size if space constraints limit the available board area. Verify that the 230V primary input matches the local mains supply standards. Evaluate the thermal performance relative to the encapsulation method used in the BV series.

Part Context

This component 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 electrical isolation. These transformers are typically used in applications where reliability and compact form factors are prioritized over high power throughput.

Replacement Considerations

The BV202D10006 is a documented alternative within the same series, offering identical physical dimensions and 0.6VA rating but with a different secondary output configuration. Verify pinout compatibility and electrical specifications before substitution.
