Aluminum-Polymer CapacitorsAluminum-polymer capacitors are a type of electrolytic capacitors. They are typically used in applications that require high-density capacitance, long life and a wide temperature range. They are also commonly used in automotive applications, due to their robustness and durability.The APXG250ARA820MH80G is a tantalum aluminum-polymer capacitor that is perfect for use in automotive applications. It has a large capacitance range of 820 to 80,000 μF and a wide operating temperature range of –40°C to +125°C. It also has excellent ESR characteristics, making it an ideal choice for automotive electronics. The aluminum-polymer capacitor is composed of an anode (the aluminum plate), a separator (the polymer layer) and a cathode (the tantalum plate). The aluminum anode is first coated with an electrolyte. This electrolyte then serves as the dielectric between the anode and the separator which forms the electrolyte interface and gives the capacitor a high energy storage characteristics. After this, the tantalum cathode is added and the capacitor is finally sealed with a case. The capacitance is determined by the size of the anode, the type of electrolyte used, the thickness of the polymer layer, and the distance between the anode and the cathode.When the capacitor is used in an electronic circuit, the positive power source is connected to the anode and the negative power source is connected to the cathode. When a voltage is applied, an electric current will flow through the electrolyte and across the anode/separator/cathode junction. This current will be stored as an electric charge, and the resulting charge will form an electric field between the anode and the cathode. This electric field is what stores the energy, and this is the main advantage of aluminum-polymer capacitors.Because of the polymer layer, the capacitance of aluminum-polymer capacitors is much higher than that of other types of electrolytic capacitors. Additionally, the polymer layer also helps to reduce the amount of leakage current and, thus, increases the life of the capacitor. The APXG250ARA820MH80G is the latest in the aluminum-polymer line of capacitors. It is a highly efficient capacitor, and it has a wide temperature range, making it perfect for use in automotive applications. Furthermore, due to its robust construction, the aluminum-polymer capacitor has an extremely long lifetime, providing reliable performance for many years.
