Yep.

So get 250mA or whatever's the closest.

A 200mA fuse doesn't blow at exactly 201mA.

Calambres:
Can't find 250mA either!


I find them in Slow Blow version but not Fast Blow as required.

floobydust:
I just noticed this meter has a bug  |O
AC mA reads zero until over 3.5mA and then reads 20% low, until over 10mA where it starts to read accurately. This is with 60Hz AC sine.

May be there is enough space for a regular fuse?

I think I saw these fuses on AliExpress, although the price was quite high.

David Hess:
Here is a brute force method that I randomly came across in the LT1011 datasheet.  The LT1011 is an improved 311 but a couple of FET buffers and a better comparator could be used for even greater performance.
