BV302D18015

Overview

The BV302D18015 is a 1.5VA encapsulated power transformer from Zettler Magnetics, designed for through-hole mounting. It features a 230V primary input and an 18V secondary output with a current rating of 42mA. The unit utilizes an EI30 laminated core construction and is fully encapsulated under vacuum pressure to ensure compactness and efficiency. Physical dimensions include a case size of 32.8x27.8mm and a height of 24.5mm.

Feature Summary

• Fully encapsulated under vacuum pressure for enhanced efficiency and compact design
• EI30 laminated core construction providing reliable magnetic performance
• Through-hole mounting configuration for standard PCB integration

Applications

• Low-power AC-DC linear power supply circuits
• Control panel isolation applications
• Small appliance internal power distribution

Procurement Notes

Verify the specific secondary voltage and current requirements against the 18V/42mA specifications before procurement. Confirm that the 230V primary input aligns with the target mains frequency and voltage stability. Ensure mechanical clearance accommodates the 32.8x27.8mm footprint and 24.5mm height for proper through-hole insertion and board spacing.

Selection Notes

Select this component when a low-profile, encapsulated transformer is required for 1.5VA loads. The EI30 core size offers a balance between physical compactness and thermal management for small enclosures. Consider the fixed 230V primary constraint if operating in regions with different standard voltages or frequencies.

Part Context

This model belongs to the BV series of encapsulated power transformers from Zettler Magnetics. The series is characterized by vacuum-pressure encapsulation techniques aimed at reducing size while maintaining electrical safety and thermal dissipation capabilities for general-purpose power conversion tasks.

Replacement Considerations

Cross-reference with other BV series variants such as BV302D06015 for different secondary outputs. Verify that substitute parts maintain identical EI30 lamination sizes and case dimensions to ensure mechanical compatibility within existing assembly fixtures.
