Procurement Notes
Verify the specific ordering suffix to ensure compatibility with required safety certifications and insulation classes. Confirm that the 230V primary input matches the local mains frequency specifications. Check datasheet details for clearance and creepage distances relevant to the target application's regulatory environment.
Selection Notes
Select this model when a 2.8VA capacity is sufficient for the load requirements. Ensure the physical dimensions fit within the available PCB space and enclosure constraints. Consider the thermal performance characteristics inherent to the encapsulated construction for the intended operating temperature range.
Part Context
This component belongs to the BV302 series of encapsulated transformers manufactured by Zettler Magnetics. The series offers various voltage configurations while maintaining consistent mechanical footprints.
