Yes, I missed the Littelfuse spelling (but not in the Hot Wheels
thread); you might want to recheck the spec re Wickmann.

Let me know if you want to stop by. I may be in Apopka, which is

It's called the same thing in the US. I've never heard it called a bucket
truck.

A cherry picker is a similar, but lighter and small vehicle used for
picking fruit. A bucket truck is too heavy and too wide to go down the
rows in most groves. A bucket truck usually has outriggers to stabilize
them when used off asphalt on concrete roads.

That's entirely possible. I've never designed with that style of fuse,
so I'm not familiar with the brands.

I tried a lot of fuse types before I settled on that one. Use four 12
Volt deep discharge vehicle batteries in series, a spool of 4/0
cabling [about 50uH], and a starter solenoid for contactor. The
circuit forms a short through the fuse. When the solenoid activates
you get about 300-500 A through the fuse and it goes off like a flash
bulb. The fuse stops conducting abruptly enough that the inductance
gives you an excellent kick back to meet BT's weird telecom -48V power
surge spec. I couldn't get any other fuse type to do as well.

I don't know of a standard term, but browsing through DigiKey
datasheets, the terms 'subminiature', 'micro', 'cartridge', and 'IEC
60127-3' are commonly used.

I've seen similar fuses on PCI extender/debug cards.
They sound like the fuses that used to be common on SCSI cards. They
look very much like small value electrolytics, except hard plastic
cases, with the value on the top, rather than on the side.
That sounds like a 'Picofuse'.
I've always known picofuses to be of axially leaded cylindrical
construction, looking like a small moulded choke package. Very confusing how
terms vary from place to place around the world ...
