CAPACITOR Checking
vinlove:
Has this capacitor gone bad? In paper, it is supposed to be 100uF.
But in checking out with the meters, it is 200 -230nF?
And Vloss= 7.1%?

Yes it's bad. Throw it out.

Thanks for advice. That cap is new, never been used. Just has been kept in the draw for 2-3 years. What could have made it gone bad?

It is normal for cheap, poor quality parts bought from ebay, AliExpress or Amazon to be bad when new, not to go bad later. I never buy cheap junk so I do not know how long they last.

Failure of a component could be due to a number of causes. Sloppy manufacture, inadequate testing, deterioration on the shelf, exposure to hostile environments, and more.
