BV302S18028

Overview

The BV302S18028 is a 2.8VA encapsulated power transformer manufactured by Zettler Magnetics, designed for through-hole mounting. It features a single primary winding rated for 230VAC at 50/60Hz and a secondary output of 18VAC with a maximum current capacity of 156mA. The component utilizes an encapsulated construction to provide electrical isolation and environmental protection. Key electrical specifications include a maximum temperature rise of 30.9°C and compliance with RoHS3 standards. The unit is intended for use in applications requiring reliable AC-to-AC voltage transformation within compact form factors.

Feature Summary

• Encapsulated construction for enhanced durability and insulation
• Through-hole termination style for secure PCB integration
• Single primary winding configuration optimized for standard line voltages

Applications

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

Procurement Notes

Verify the specific datasheet version provided by Zettler Magnetics or authorized distributors to confirm mechanical dimensions and thermal characteristics. Ensure that the 230VAC primary rating aligns with the target application's input supply frequency and voltage tolerance. Confirm RoHS3 compliance requirements are met for the intended market regulations before finalizing procurement orders.

Selection Notes

Select this component when a low-power, encapsulated transformer is required for general-purpose AC power conversion. The 2.8VA rating suits light loads such as control circuits or indicator modules. Consider the through-hole package constraints during PCB layout design. Verify that the 18V secondary output matches the downstream circuit requirements without excessive regulation needs.
