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 Schematics unpublished.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, Dave

Jeez. Yer an idiot.
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: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. ;-)
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.
Could that be because no one knew what tghe question was?

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

Obviously, it's 10,000,000 amperes ;^)
