Capacitor Values

[gerhard123]

I should've said this. I'm a musician, I need a capacitor for my tone control. I needed a .015 cap disc or whatever. The store gave me a .0015M. Is this correct??

No, as we've already said it's 10 times too small.

.015 looks more like .015nF. Does it have the full value labeled or just .015?

Apply a little common sense, do you think 15pF would be any use for a tone control? - you also don't use nF below 1nF, you switch to pF anyway.

no, it's 15nF. the OP needs 0.015uF. usually 0.015 with no other information (the "M" on the OP's cap from the store is the temperature coefficient) means 0.015uf. microfarads are assumed, unless the caps are very small, in which case, picofarads are assumed. caps newer than about the year 2000 will be marked with a 3 digit code, such as 153. you have two significant digits and a multiplier. 153 would be the correct code for the value of cap the OP is looking for.

Thank you, I appreciate the explanation. I was glancing at conversion chart I had for caps and the one that stood out for for .015 was nf, but I see where my error was now.
