BV301D12020

Overview

The BV301D12020 is a laminated power transformer from the BV series by Zettler Magnetics. It features an EI30 core size and operates with a 115V primary input at 50/60 Hz. The unit provides a dual secondary output of 2x12V, delivering a rated current of 83mA per winding for a total capacity of 2VA. The component utilizes through-hole mounting technology and is fully encapsulated under vacuum pressure to ensure compact dimensions of 32.8x27.8mm with a case height of 27.4mm.

Feature Summary

• Fully encapsulated construction under vacuum pressure for enhanced efficiency and compact form factor
• Laminated EI30 core design optimized for linear power supply applications
• Through-hole termination style for standard PCB integration

Applications

• Linear power supply circuits
• Electronic equipment requiring isolated AC voltage conversion
• Control panel power distribution

Procurement Notes

Verify the specific datasheet version for the BV301D12020 to confirm insulation class and safety certifications required for your target market. Ensure that the 115V primary rating aligns with your local mains frequency standards. Cross-reference the encapsulation specifications against environmental operating conditions to validate long-term reliability in your specific deployment scenario.

Selection Notes

Select this component when a compact, encapsulated transformer is needed for low-power linear applications. The 2VA rating suits small signal processing or control logic power stages. Verify that the physical footprint fits within the enclosure constraints due to the fixed encapsulated housing dimensions. Confirm that the dual 12V secondary configuration matches the downstream rectification requirements.

Part Context

This part belongs to the BV series of encapsulated power transformers manufactured by Zettler Magnetics. The series is characterized by vacuum-pressure encapsulation techniques designed to reduce size while maintaining electrical performance. These transformers are engineered for general-purpose power conversion tasks where space efficiency and mechanical stability are prioritized over high-frequency operation.

Replacement Considerations

Direct substitutes must match the 2VA rating, 115V primary, and 2x12V secondary configuration. Verify that alternative components maintain the same EI30 core geometry and through-hole pinout to ensure mechanical compatibility without PCB redesign.
