Procurement Notes

Verify the specific datasheet version when ordering, as manufacturing revisions may occur. Confirm that the 115V primary rating aligns with your local mains voltage standards or required input conditions. Ensure the through-hole footprint matches the target PCB layout dimensions of 32.8x27.8mm. Check for any regional regulatory certifications required for the end application market.

Selection Notes

Select this component when a compact, encapsulated solution is required for low-power applications under 1VA. The 115V primary specification suits regions utilizing this voltage standard or specific control circuit inputs. Consider the 70°C temperature limit for thermal management in enclosed spaces. The EI30 core size offers a balance between magnetic performance and physical footprint for space-constrained designs.

Part Context

This part belongs to the BV Series of encapsulated power transformers from Zettler Magnetics. The series covers output loads ranging from 0.6VA to 10VA, providing standardized solutions for various consumer and industrial electronics. These transformers are characterized by their sealed construction, which protects internal windings from moisture and contaminants, ensuring reliability in diverse operating environments.

Replacement Considerations

Direct substitutes must match the 1VA rating, 115V primary, 18V secondary, and EI30-10.5 core form factor. Verify that alternative components maintain Class 2 insulation ratings and through-hole compatibility. Cross-reference pinout configurations and dimensional tolerances to ensure mechanical fit within the existing assembly without modifying the PCB layout.
