- Thermostats
Procurement Notes
Verify the specific part number suffix against official Zettler Magnetics documentation to confirm electrical characteristics and mechanical footprint. Ensure compatibility with target PCB layout requirements for through-hole installation. Cross-reference datasheet specifications for thermal performance and insulation ratings prior to integration into final designs.
Selection Notes
Select this model for applications requiring a compact, encapsulated transformer with a 2.8VA rating. The 115V primary input suits regions utilizing standard line voltages. Dual 9V secondaries provide flexibility for rectification circuits. Consider the EI30 core size constraints when designing enclosure spaces for linear power supplies.
Part Context
This component belongs to the BV Series of encapsulated power transformers manufactured by Zettler Magnetics. The series utilizes laminated cores fully encapsulated under vacuum pressure to achieve smaller sizes and improved efficiency compared to non-encapsulated alternatives. These transformers are engineered to meet stringent design requirements for off-line and SMPS power sources.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official Zettler Magnetics documentation or authorized distributors for equivalent models with matching VA ratings, voltage configurations, and mechanical dimensions.
