... ADM2582E/ADM2587E transformers. Figure 26 expresses these allowable current magnitudes as a function of frequency for selected distances. As shown in Figure 26, the ADM2582E/ ADM2587E are extremely immune and can be affected only by extremely large currents operated at high frequency very close to the component. For the 1 MHz example, a 0.5 kA current would need to be placed 5 mm away from the ADM2582E/ ADM2587E to affect component operation ...

... Operation at working voltages higher than the service life voltage listed leads to premature insulation failure. The insulation lifetime of the ADM2582E/ADM2587E depends on the voltage waveform type imposed across the isolation barrier. The iCoupler insulation structure degrades at different rates, depending on whether the waveform is bipolar ac, unipolar ac ...
