Partial Jag failure?

[kamocat]

Ah, I understand now.

I was thinking of aluminum shavings only affecting large circuits, and destroying them in doing so. I hadn't considered that it might make a contact across a small circuit, and not damage anything in the process. Even more so, I hadn't considered that they might, in effect, put the Jaguar in a fault condition that it can't detect. I don't know that it was in a fault condition, but it's either that or the limits, and I'm pretty sure the limits were not active.

These Jaguars really need a conformal coating. It would be interesting to compare the failure rate. In fact, if I had a few thousand dollars to spare, I would buy Jaguars, paint them with polyurithane, and sprinkle aluminum dust on them to see how well they survive.
But because of the cost, I think that's something best done by TI.
