Camcorder/camera fuse identification
 

I'm trying to identify and also find a source for some camcorder and
camera fuses. Both are used in Canon products. They are surface mount,
VERY small, and one has a K on it and the other a H. The camcorder says
one of the fuses is a littelfuse 494001 but I can't find that fuse. Can
anyone help me identify these two fuses? I have seen them in the Canon
Digital Rebel and the XT and a Canon Optura 100MC and Optura 200MC. I
want to chose the right value and also use the same physical size since
they are VERY small. I have small surface mount fuses but these are
Nano size.
Thanks for any info.
