Procurement Notes

Verify the specific suffix 'AED' against the manufacturer's current datasheet to confirm termination plating and packaging details. Ensure the design accommodates the specified 1500 Vrms isolation requirements and thermal limits. Cross-reference the 12.5 µH primary inductance tolerance with system specifications before finalizing the bill of materials.

Selection Notes

Select this component when designing isolated flyback power supplies requiring high voltage isolation between primary and secondary sides. The 12.5 µH inductance value is critical for determining switching frequency performance. Consider the 4-42V input range compatibility with the target controller chipset, such as Texas Instruments solutions, during the schematic phase.
