John, it is a /Thermal/ Fuse, i.e. it fails open when it gets above a 
certain temperature, in this case I think about 105°C.  I bought a bunch 
of 20 of the Panasonic ones when they were still available from Digikey; 
I could stick one in an envelope and mail it to you.

Personally I think it's a really bad idea to link it out, and would be 
surprised if -hp- recommended this.

Anyway I'll go look for the packet :^)
