BV301D09018

Overview

The BV301D09018 is a 1.8VA encapsulated power transformer from the Zettler Magnetics BV Series, designed for through-hole mounting. It features an EI30 laminated core with a case dimension of 32.8x27.8mm and a height of 24.5mm. The unit operates with a primary input voltage of 115VAC and provides a dual secondary output of 2x9VAC at 100mA per winding. It supports a maximum operating temperature of 40°C and weighs approximately 80g.

Feature Summary

• Encapsulated construction for environmental protection
• Through-hole pin configuration for PCB integration
• Dual secondary windings for split voltage requirements

Applications

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

Procurement Notes

Verify the specific datasheet version to confirm regulatory certifications such as UL recognition. Ensure the 115V primary rating matches the local mains supply or requires a step-up configuration. Confirm that the 1.8VA capacity meets the load requirements of the target circuit design before finalizing procurement.

Selection Notes

Select this component when a compact, low-power isolation solution is required for 115VAC applications. The EI30 core size offers a balance between physical footprint and magnetic performance. Consider the dual 9V output if balanced rectification or split-rail logic supplies are needed in the downstream circuitry.

Part Context

This part belongs to the BV Series of encapsulated power transformers, which are engineered for reliability in consumer and industrial electronics. The series utilizes standard EI laminations and epoxy encapsulation to provide mechanical stability and electrical insulation suitable for mass production environments.

Replacement Considerations

Direct substitutes include other BV301 variants with different secondary voltages, such as BV301D09012, provided the voltage ratings align with the application needs. Cross-referencing core size (EI30) and VA rating is essential for mechanical fit.
