Procurement Notes

Verify the specific part number against official Zettler Magnetics documentation to confirm electrical ratings and mechanical dimensions. Ensure that the through-hole mounting style aligns with your printed circuit board layout requirements. Cross-reference the encapsulation type and core lamination size to guarantee compatibility with your thermal and spatial constraints before finalizing procurement decisions.

Selection Notes

Select this component when a 2VA power rating and 18V secondary output are required for single-phase applications. The encapsulated design offers protection against environmental factors while maintaining a small footprint. Consider the through-hole mounting requirement and verify that the 230V primary input matches your system's available voltage source and frequency specifications.

Part Context

This transformer belongs to the BV series of encapsulated power transformers manufactured by Zettler Magnetics. The series utilizes EI30 laminated cores and vacuum pressure encapsulation techniques. These components are engineered to provide smaller, more efficient solutions for linear power supplies compared to non-encapsulated alternatives, serving as a reliable power conversion stage in various electronic assemblies.

Replacement Considerations

Consult official Zettler Magnetics substitution guides or datasheets for confirmed equivalent part numbers. Do not assume cross-compatibility based on similar VA ratings or voltage outputs alone. Verify mechanical dimensions, pin configurations, and insulation class requirements to ensure safe replacement within the existing design architecture.
