I'm here with NVE's Quality Guru. Dee, do IsoLoop isolators really last "forever"?
For practical purposes, forever.
Optos use LEDs, which degrade over time. Every photon
emitted depletes the LED, so the output decreases and eventually it will fail.
That's one reason engineers hate optos.
Sure. But IsoLoop isolators use magnetics and spintronics rather than optics.
Nothing is depleted. Nothing degrades with time.
Think of a microwave versus an Easy Bake oven.
Neat. But What about the life of the isolation barrier?
The isolation barrier is a patented glass-polymer structure that doesn't degrade. Compared to
conventional semiconductors, it’s like indestructible fiberglass versus rusting sheet metal.
Do you have data to back that up?
Absolutely. Our reliability data show failures-in-time of 2.6 per billion hours at 100 degrees C,
for an MTBF of 44,000 years. Some conventional semiconductor isolators brag about a barrier
life of just 13 years.
Thirteen years gives engineers "fits." Heck, even my ties last longer than that.
So you've had parts on life test since the Pleistocene era?
Well, at least since the Reagan administration, with standard FITs extrapolations.
Thanks, Dee. How can viewers get IsoLoop reliability reports?
