BV302D15018

Overview

The BV302D15018 is a 1.8VA encapsulated power transformer from Zettler Magnetics, designed for through-hole mounting. It features a 230V primary input and dual 15V secondary outputs, each rated at 60mA. The unit utilizes an EI30 laminated core with a height of 12.5mm. Physical dimensions are 32.8x27.8mm with a case height of 24.5mm. It operates within a 40C temperature class and weighs approximately 80g.

Feature Summary

• Fully encapsulated under vacuum pressure for enhanced efficiency and compactness
• Dual secondary windings providing isolated 15V outputs
• Through-hole construction suitable for standard PCB assembly

Applications

• Linear power supply circuits requiring low voltage isolation
• Electronic devices utilizing 230V AC mains input
• Control systems needing dual low-voltage DC rails

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct electrical tolerances and insulation ratings. Confirm that the through-hole pin configuration matches the target PCB footprint. Check for any recent updates to the EI30 series specifications regarding thermal performance or regulatory compliance before finalizing procurement.

Selection Notes

Select this component when a 1.8VA capacity is sufficient for the load requirements. Ensure the application environment supports the specified 40C temperature class. Verify that the physical envelope of 32.8x27.8mm fits within the available board space. Consider the dual 15V output configuration if separate positive and negative rails are required for the circuit design.

Part Context

This model belongs to the BV Series of encapsulated power transformers from Zettler Magnetics. These units are characterized by vacuum-pressure encapsulation, which improves thermal dissipation and mechanical stability compared to non-encapsulated variants. The EI30 lamination size provides a balance between power density and physical footprint for general-purpose applications.

Replacement Considerations

The BV302S15018 is a related variant within the same series. Verify if the 'S' suffix indicates differences in packaging or specific regulatory certifications. Cross-reference the BV301D18018 for potential alternative configurations within the EI30 family, ensuring all electrical parameters remain compatible.
