Thanks, Kevin.

They way Littelfuse uses a stylized "LF", it could easily be mistaken for
"1E" or "lE".

Now to get one...

Thanks again,
Dave

No, I don't have one. I threw it out with the old battery. :-(
Someone on-line volunteered to describe the one from his scope.
I'll not ask him to do a post-mortem on a working fuse. ;-)

Thanks,
Dave

Fuse.
Ratings of these beasts in equipment is almost NEVER disclosed - like
a company secret more precious than any other secret they have.
Measure current draw and see what the maximum is during any
operations, double that for a guide in choosing "first guess" replacement.

The axial leaded jobs I have seen in hair dryers are high current jobs
with reed switches inside them. Not the soft break jobs.

The biggest soft device I recall was 3 Amps.
