I took a close look at a spare Motorola MTR2000 fuse, part number 6583049X16, and can provide some additional data: The fuse is rectangular, with a square cross-section, and measures about 6.0mm by 2.6mm. It has a ceramic body, with silver-plated end caps. The legend "IE5A" is printed on one face.
This fuse seems to be identical to Littelfuse (note the spelling) Series 453 "Nano" fuses.

I forget their exact part designation but several models of hospital beds uses them. I had never seen them before and unfortunately got them from the mfgr. of the beds because I needed some overnight and didn't have time to search. I got about 10 of each (they range from 0.5 to 7 amps @ 32 VDC) plus fuse holders for each one for $200. (sigh) I can't give any of the fuses away, but if anyone wants any surface- mounts for these fuses, I think I have about 30 of them that I could give away. :-) Anyway, Newark stocks them, too. :-) Ray, KBØSTN
