Thanks Soren - it may be a while before I have access to the necessary
tools, but once I do I will give that a try.

I should add, that this is why

Hi
When used as a fuse a ferrite bead generally does a poor job. They
will move quite a bit of current before they explode. I seem to prove
that every so often ...

Try just to measure the resistance in the non-fried device.

battery bank when a short occurred. This killed the net4801 rather
effectively, but from looks alone it seems that one particular
component may have sacrificed itself alone to save the rest as
