I tested old(30-50 years old) 100uF capacitors with my Extech LCR meter. The measured Q values were from 0.5 to 1.5 while measured capacitance values were from 100 to 500uF. A new freshly made 100UF capacitor measured 100uF, and Q of 9. My questions is what is the appropriate value of Q for a good electrolytic capacitor?
