I have a question regarding the unit of capacitors. I thought the
units are pf, u, or f.
For example, a capacitor could be 0.01 uf; another could be 470
pf. But today I saw one that says on its body 560 k. I thought that
is
a unit resistors use, for example, a resistor could be 100om or 400K.
So I am puzzled. Anybody has any enlightening ideas?
Best wishes to you! Dan

** If "K" is marked on a cap after the value, it generally indicates that
value has a tolerance of +/- 10%

"J" indicates 5%.

Thanks for your help! In addition to J abd K, are there any other
letters used to indicate tolerance, like A through Z?
Best! Dan

** "F" = 1%

"G" = 2 %.

"M" = 20%

The K isn't a unit, but a tolerance code. See:

It's short for 560pF. K is the tolerance (10%).
