Used in the battery (-) lead of a handheld scope. Schematics unpublished.

Physically similar to a 1/4 W resistor, color light green. Marked "IE7A" or
"1E7A".

Google returns slim results, none promising.

What type is this?

I should have figured that not a goddamned soul actually tried to answer
the question.

It sounds like a 'soft-fuze'. That resets itself after tripping.

There is also a similar device used in hair dryer circuitry.

** Sounds like a Pico Fuse:

http://media.digikey.com/photos/Litt...1%20SERIES.jpg

Come in fast and very fast ratings with amps rated from 1A to about 15A.

When they blow, you need a soldering iron to replace them.

There are various Asians clones too.

** Sure that is not the other way around ?

Pico Fuse would use " 7A LE " as a the marking for a 7 amp fuse.

I take it , that its blown and I also take it that its not charred (fusible
R don't char or even discolour AFAIK)
Desolder it and scrape an axial line along its length . Then DVM resistance
check from either end. If a fusible resistor then maximum R read is what its
value was near enough.
FR breaks are usually to one end, normal R usually in the middle.
Although green is often axial inductor.

Littlefuse makes green resistor-shaped fuses. Their logo is an 'L'
wrapped under an 'F' so their 'LF' could look like 'IE' on a worn part.

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. ;-)

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.

If you cannot glean the question from that, you are not only too

Nice sig, dumb****. It fits you perfectly.

And that's why markings are so important. You can circumvent any need to
measure.

and several other fuse manufacturers list E as .375A. If you read the
data sheets, you should be able to determine what family you need.

They won't catch fire but I have seen them char slightly. It's also
common for them to crack or blow out a small chip of ceramic if
something shorts and exposes them directly to the line voltage.
