I was curious if the tolerance values are important when replacing capacitors. I don't mean can a replace a %10 with a %20 or something like that but the other way around. Specifically, the .01uf +80 -20. Can I replace that with a ±10?
Quoted from ForceFlow:The percentage value is the tolerance of a capacitor's capacitance. The lower the tolerance (percentage), the more precise the capacitance.
You can usually go to a lower tolerance (percentage) value without any problems.
Also pay attention to the working voltage value. You can usually use a replacement with a higher voltage, but it's usually not a good idea to go lower.
Most of the time, it's standard for .01uF capacitors used in pinball machines to be 10% tolerance.
Thanks for the response. I have the basics down on that, tolerance voltage capacitance ect. I just found it strange that the tolerance was listed as +80 -20. I wasn't sure if that was important in it's operation in some way. Just seemed strange but I guess it's just an old cheap cap?
The one I'm referring to is 5A-8980 on the Williams system 6 driver board.
Quoted from G-P-E:+80%/-20% -- standard ceramic bypass capacitor tolerance.
Doing a little research I see that the decoupling cap value is not all that critical. So I guess that means the tolerance didn't have to be that accurate. I assume I should be fine replacing it with a standard 10% .01mfd 50v axial ceramic. I just wasn't sure if it was a special cap in some way.
