Power Transformers Procurement Notes

Verify the specific datasheet version to confirm insulation class and safety certifications such as UL or IEC standards. Ensure the 115V primary rating matches the local mains supply frequency and voltage tolerance. Confirm that the through-hole footprint dimensions align with the target PCB layout before finalizing procurement decisions.

Power Transformers Selection Notes

Select this component when a low-power, encapsulated transformer is required for direct AC-to-AC isolation. The 1.5VA rating suits small signal circuits rather than high-load applications. Consider the physical dimensions of 32.8x27.8mm for enclosure space constraints. Verify thermal performance requirements against the encapsulation type.

Power Transformers Part Context

This part belongs to the BV Series of encapsulated power transformers from Zettler Magnetics. The series is engineered for off-line and SMPS power sources, meeting stringent design requirements. These components are widely used in appliances, industrial controls, and medical equipment where compact size and reliability are critical.

Power Transformers Replacement Considerations

Check for exact pinout compatibility and VA rating equivalence when substituting. Verify that alternative models maintain the same 115V primary and 18V secondary specifications. Ensure mechanical fit within the existing PCB hole pattern and enclosure space.
