AI Customer ServiceThere are various brands of capacitors on the market. Made in China, made in Taiwan, Korean and Japan brands. 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?
Too often we get / give the advice to replace all electrolytic capacitors on a PCB when it starts to malfunction (like in DVD player power supply circuit strange behavior. Need help to understand root cause but here are many more examples). Reason seems to be the huge difference in quality for these capacitors.
You don't check. To choose the capacitor, you go to the manufacturer data sheets of the capacitors, which will have the specifications you need to help you choose. You buy from a reputable distributor, and specify the capacitor you want. That way, counterfeits and substitutions are less likely.
You also need to know that the application isn't over-stressing the capacitor. A bad design that leads to excess ripple current or operating temperature or excessive voltage (or some combination of the three) may cause even the best capacitors on the market to fail prematurely.
A good cap in a circuit with good design margins should last years without issues, as the design will accept some degradation of the capacitor over time before failing. Only when you know these two factors would you even be in a position to judge why a capacitor failure occurred. You need to trust your supplier.
Using a general-purpose capacitor in a circuit that needs a high ripple, low-impedance capacitor is a prime example of where things can go bad quickly. A good cap in a circuit with good design margins should last years without issues, as the design will accept some degradation of the capacitor over time before failing.
