Fuse or fusible resistor?
 

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 Schematics unpublished.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?

Thanks,

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,

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
goddamned retarded to be answering it, you are too goddamned retarded to
be in the group at all, much less being here, acting like you have half a

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

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

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.
