Aluminum electrolytic capacitors are divided into two categories: wet type and dry type. The ELZA160ELL821MJC5S belongs to the wet type of aluminum electrolytic capacitors. That means it has a solid, gaseous or liquid electrolyte as the medium between its two power plates made of aluminum foil. The ELZA160ELL821MJC5S is suitable for applications where capacitance values are limited and operating voltages are relatively high.The working principle of the ELZA160ELL821MJC5S can be understood as an electrochemical cell which consists of two power plates- an anode and a cathode- separated by an electrolytic medium. The anode is made of aluminum foil on which a layer of aluminum oxide is grown during the manufacturing process. The oxide layer acts as an insulator and provides a much higher working voltage when compared to others capacitors. The cathode is made of metallic aluminum and it is tied to the case that holds the device. The electrolyte can be any of the three – a solid, a gas or a liquid. The main function of the ELZA160ELL821MJC5S is to store an electric charge for a period of time and deliver it when required. The anode plate is connected to the positive terminal of a voltage source and the other plate is connected to the case, thus making it the negative terminal. When voltage is applied across these two terminals, a capacitive element is formed. When the voltage is greater than the driven voltage, electric current flows from the cathode to the anode. The current is used to ionize the electrolyte, thus creating an electric attraction that stores the charge on the anode plate and negating it on the cathode plate. In summary, the ELZA160ELL821MJC5S aluminum electrolytic capacitor is ideal for applications requiring relatively high values of capacitance with limited operating voltages. Also, due to the electrochemical reaction, it can store charge for a long period of time and can be used as a source of quick energy when needed.
