I dont know where you get 102 degrees C from. That is barely above boiling point.
To get an estimate as to how hot they get, I tested them with some tin/lead solder that melts at 180 degrees C. Whilst it didnt melt it, it did soften it. On this basis I would estimate their temperature as around 160 degrees C.
Hence, on this basis a fuse of about 190 degrees C should be OK. However, if you know where to get one from, please let us know!
