breakdown voltage determines the maximum voltage to which the capacitor can be charged to and limits the operating voltage of a circuit incorporat-ing the capacitor. However, in many applications a capacitor not operate at high voltages, so this parameter is less important in these cases. The leakage current likewise determines the time a capacitor can hold its charge; if the …
