Procurement Notes

Verify the specific datasheet version and pinout configuration before integration, as isolation transformers require precise alignment with system voltage ratings. Confirm that the 2300VDC isolation rating meets the safety requirements of the target application environment. Ensure the five-terminal layout matches the PCB footprint design to prevent electrical shorts or open circuits during assembly.

Selection Notes

Select this component when a specific 1.43:1:1 transformation ratio is required for isolated signal coupling. The 820uH inductance value must align with the frequency response needs of the driving circuitry. Consider the thermal performance and physical dimensions of the SMD package relative to the available board space and cooling constraints within the enclosure design.
