Get PriceHow can we measure the quality of a capacitor?
Although the values of the capacitors are the same (eg. 35 volts 2200 uf) some capacitors come out more robust and longer life. How can I measure the difference in quality? I can measure the capacitance with a multimeter, and I can measure the ESR with an LCR meter. How else do you check? For example, I cannot test the operating voltage.
