BV302D09028

Overview

The BV302D09028 is a 2.8 VA encapsulated power transformer from the Zettler Magnetics BV series, designed for through-hole mounting. It features a 230V primary input operating at 50/60 Hz and provides a dual 9V secondary output (2x9V) with a current rating of 156mA per winding. The component utilizes an EI30 lamination size within a compact case measuring 32.8 x 27.8 mm and a height of 29.8 mm. This model supports wide AC input ranges typical of the series, ensuring reliable voltage transformation for low-power applications requiring galvanic isolation.

Feature Summary

• Encapsulated construction for environmental protection and mechanical stability
• Through-hole mounting configuration for standard PCB assembly
• Dual secondary windings providing isolated 9V outputs
• EI30 core lamination size for efficient magnetic performance

Applications

• LED lighting systems
• Electric metering devices
• Motor controls
• Thermostats

Procurement Notes

Verify the specific ordering suffix to confirm the exact secondary voltage configuration and insulation class. Ensure compatibility with the target PCB hole spacing and thermal requirements during integration. Confirm RoHS compliance status if required by regulatory standards. Cross-reference the manufacturer datasheet for detailed electrical characteristics and safety certifications before finalizing the design.

Selection Notes

Select this component when a 2.8 VA capacity is sufficient for the load requirements. The dual 9V output is suitable for circuits needing split supplies or redundant isolated rails. Consider the physical dimensions of 32.8 x 27.8 mm for board layout constraints. Evaluate the through-hole technology against surface-mount alternatives if space or automation processes dictate different assembly methods.

Part Context

This transformer belongs to the BV Series of encapsulated power transformers from Zettler Magnetics. The series is engineered for off-line and SMPS power sources, meeting stringent design requirements. The BV series is widely used in appliances, industrial controls, medical equipment, and energy management systems, offering a balance of performance and reliability for various global markets.

Replacement Considerations

Direct substitutes include other BV series variants such as BV302S09028 or BV302D10028, depending on whether encapsulation type or secondary voltage needs adjustment. Verify that any replacement maintains the same VA rating, primary voltage, and physical footprint to ensure seamless integration without redesigning the PCB.
