Aluminum - Polymer Capacitors Aluminum - polymer capacitors, also known as “super capacitors” or “ultra capacitors”, are a type of energy storage device capable of storing energy for longer periods of time than traditional electrolytic or film capacitors. The primary difference between aluminum - polymer capacitors and traditional capacitors is their ability to store charge for significantly longer times. An aluminum - polymer capacitor consists of an electrolyte between two electrodes, with the electrolyte typically being a polyphenylene sulfide (PPS) material. The electrodes consist of an anode and a cathode, with the electrodes either having an electrostatic (charge-storage) or non-electrostatic (charge-transport) property.EEF-SD0J121R is a type of aluminum-polymer capacitor developed by Electrical Energy Co., Ltd. The capacitor has a max. operating temperature of 85°C, an operating temperature range of -40°C to 85°C, and a rated voltage of 12V. It has a cylindrical shape and is made up of four parts: a dielectric, an anode, a cathode, and a conductor to provide electrical connection between the anode and cathode. The capacitor has a capacitance of 0.12F and a rated ripple current of 40mA.EEF-SD0J121R has many applications in various industries. Capacitors of this type are often used in battery backup systems, LED lights, solar and wind power applications, and other high-power applications. The capacitor’s long service life and high temperature range make it suitable for use in harsh and unstable environments. The capacitor also offers high power density, which makes it ideal for power backup applications.The working principle of EEF-SD0J121R is based on the properties of its electrodes. The capacitor has two sets of electrodes, which have either an electrostatic or non-electrostatic property. When a voltage is applied to the capacitor, the charges migrate between the two sets of electrodes, and the energy is stored in the form of electrostatic fields between them. This energy is released when the capacitor is discharged.The capacitor\'s dielectric serves to insulate the charge carriers and thus prevent short circuiting. The anode and cathode act as the two electrodes, with the anode being the conductor and the cathode being the non-conductor. The anode is composed of a conducting material and is connected to the negative terminal of the power source. The cathode, on the other hand, is composed of a non-conducting material and is connected to the positive terminal of the power source.In conclusion, the EEF-SD0J121R is an aluminum-polymer capacitor that is highly utilized in industrial settings because of its ability to store charge for longer periods of time than traditional capacitors. The capacitor exhibits high power density, making it ideal for powering applications, and its long service life and high temperature range make it suitable for use in harsh and unstable environments. The capacitor’s working principle is based on the property of its electrodes, with the anode and cathode acting as the two electrodes and the dielectric providing insulation from short circuiting.
