Overview
The BV302D18023 is a laminated power transformer from the BV series by Zettler Magnetics. It features an EI30 core with a primary input voltage of 230V and dual secondary outputs of 18V each, providing a total apparent power rating of 2.3VA. The unit operates at 50/60Hz frequencies and utilizes through-hole mounting technology. Physical dimensions include a case size of 32.8x27.8mm with a height of 29.8mm. The transformer is fully encapsulated under vacuum pressure to ensure efficiency and compactness.
Feature Summary
- Fully encapsulated construction under vacuum pressure for enhanced efficiency
- Laminated EI30 core design supporting linear power applications
- Through-hole mounting configuration for standard PCB integration
Applications
- Linear power supply circuits
- Industrial control systems requiring isolated power
- Electronic equipment needing compact encapsulated transformers
Procurement Notes
Verify the specific ordering suffix against official Zettler Magnetics documentation to confirm electrical characteristics and physical dimensions. Ensure compatibility with existing PCB layouts regarding through-hole spacing and case height constraints. Cross-reference datasheet specifications for thermal performance and insulation ratings prior to final procurement decisions.
Selection Notes
Select this component when a compact, encapsulated transformer with 230V primary input and dual 18V secondary outputs is required. The 2.3VA rating suits low-power linear applications. Verify that the EI30 lamination size and through-hole form factor align with mechanical assembly requirements and available board space constraints.
Part Context
This model belongs to the BV series of encapsulated power transformers manufactured by Zettler Magnetics. The series is characterized by vacuum-encapsulated laminated cores designed for smaller, more efficient linear power solutions. The BV302D18023 specifically utilizes the EI30 lamination size within this product family.
Replacement Considerations
Consult official Zettler Magnetics substitution guides or distributor cross-reference tools for verified equivalent part numbers. Do not assume functional interchangeability based solely on similar VA ratings or voltage configurations without confirming pinout and dimensional compatibility.
