BV301S18023

Overview

The BV301S18023 is a 2.3VA encapsulated power transformer manufactured by Zettler Magnetics, designed for through-hole mounting. It features a single primary winding rated for 115VAC input and a single secondary winding providing an 18VAC output at a maximum current of 128mA. The component utilizes EI30 laminations and is fully encapsulated under vacuum pressure to ensure compactness and efficiency. Key electrical specifications include a 115V primary voltage and an 18V secondary voltage with 128mA current capacity.

Feature Summary

• Fully encapsulated construction using vacuum pressure for enhanced structural integrity and environmental protection
• Utilizes EI30 laminated core design to support efficient magnetic flux and compact physical dimensions
• Supports standard through-hole installation via PC pin termination style for reliable circuit board integration

Applications

• LED lighting systems requiring isolated low-voltage AC power
• Electric metering devices needing compact isolation transformers
• Motor control circuits utilizing encapsulated power components
• Thermostat applications demanding reliable linear power conversion

Procurement Notes

Verify the specific part number BV301S18023 against official manufacturer documentation to confirm compatibility with your design requirements. Ensure that the 115V primary and 18V secondary ratings align with your system's electrical parameters. Check for RoHS compliance status and verify that the through-hole package fits your PCB layout constraints before finalizing procurement decisions.

Selection Notes

Select this component when a compact, encapsulated transformer is required for low-power applications. The 2.3VA rating suits devices like LED drivers and meters. Consider the EI30 core size and through-hole mounting if space allows. Verify that the 115V input matches your supply voltage and that the 18V output meets load requirements without exceeding the 128mA limit.

Part Context

The BV301S18023 belongs to the BV series of encapsulated power transformers from Zettler Magnetics. This series is characterized by its use of vacuum-encapsulated laminated cores, offering a balance between size reduction and performance. The BV series is widely used in industrial and consumer applications where reliable isolation and compact form factors are essential for power supply designs.

Replacement Considerations

Consult the official Zettler Magnetics datasheet or distributor catalogs for direct substitutes within the BV series. Verify that any replacement maintains the same 2.3VA power rating, 115V primary, 18V secondary, and 128mA current specifications. Ensure mechanical compatibility regarding the EI30 core size and through-hole pin configuration.
