Re: 475 questions


 

I'd seen specs like that but hadn't thought of it that way. A 10uF +150% - 100% would then be in spec at 10uF to 15uF. That makes a lot more sense now!

Thanks,

Hi Eric,

I think in the case of the +150% - 100% rated capacitor,
they were using the "-" as a hyphen, not a minus sign.

I think they meant to convey that the capacitor could range
in value from 150% of the marked value to 100% of the marked
value... otherwise it makes no sense to me.

In most cases, the range is as you would suppose.

There are 2 fundamental differences that need to be taken in to account

replacing “vintage” caps. And I use the term vintage loosely. One is
tolerance. In
the worst case I can remember a capacitors value was +150% -%100 tolerance.
