Is it normal to measure the capacity of capacitor 68uf to 74uf?

generally, the capacitance has a certain error +/-2%, which is normal. If it is an electrolytic capacitor, the electrolyte will slowly dry up after prolonged use, and the capacitance will decrease.

if only the nominal capacity is written on the capacitor, there is a default error. The default withstand voltage is 5V, which is estimated to be M-class, 2%. No.

generally, for capacitors without any error marks, the default error is 5%, and the default withstand voltage is 5v. What about ceramic chip capacitors and monolithic capacitors? The accuracy is also 5%? Jokes. This is the most used capacitor.
