Aluminum electrolytic capacitorrated capacity with the preferred number of series E 6, that is: (n = 0,1,2.5) ; a total of 6 values: 1uF, 1.5uF,2.2uF,3.3uF, 4.7uF, 6.8uF.

The allowed deviation is ± 20% for series E 6, but for general purpose electrolytic capacitors, the positive deviation is usually relaxed to + 50% . The loss factor of  aluminum electrolytic capacitoris defined as the ratio of active power and reactive power consumed by the capacitor under the sine voltage of the specified frequency, i. e. , where F is the frequency of the sine voltage, c is the capacity of the electrolytic capacitor series model at this frequency, R is the Equivalent series resistance of the electrolytic capacitor (ESR) . The leakage current of an aluminum electrolytic capacitor is usually defined as the current that flows through the capacitor after several minutes of applying a rated operating voltage.

In general, the maximum allowable leakage current of an aluminum electrolytic capacitor can be defined as follows:

IL = KCU (ΜA) where C is the capacitance of the capacitor (ΜF) , U is the value of the applied DC voltage (V) , and K is a constant with respect to the type of capacitor, the value range is usually 0.01-0.1, low leakage current series also have a value less than 0.002. Rated operating voltage is the maximum DC voltage that can be applied to an electrolytic capacitor within the specified ambient temperature range. Press GB2472 Rated voltage series for electrolytic capacitors are: 4V, 6.3V, 10V, 16V, 25V, 35V, 50V, 63V, 100V, 120V, 160V, 250V, 300V, 450V, 500V, 630V.

According to the actual needs, sometimes also use 200V and 350V products.
