Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are capacitors that use a chemically formed oxide film on their anode as the dielectric layer. The oxide film is formed as a result of a chemical reaction between the anode and the electrolyte, giving the capacitor its name. This type of capacitor has several advantages, such as being inexpensive to manufacture, and having a relatively large capacitance for its size. However, due to the nature of the oxide film, these types of capacitors also have some disadvantages, such as limited temperature range and relatively short life compared to other types of capacitors.

UPM1E102MHD1TO Application Field and Working Principle

The UPM1E102MHD1TO aluminum electrolytic capacitor is a polarized, non-solid electrolyte capacitor. It has a capacitance of 1.0μF with a rated operating voltage of 10V and an operating temperature range of -55 - +105°C. These capacitors are designed for use in high voltage applications due to their high stability and extremely low leakage current. They are used in applications such as decoupling circuits, noise filtering, and energy storage. The UPM1E102MHD1TO capacitor works on the principle of electrochemical reaction. The construction of the capacitor contains two positive electrodes, one negative electrode, and an electrolyte that serves as the dielectric. The negative electrode is composed of a metal plate or foil, typically aluminum. The positive electrodes are composed of an electrically conductive layer, usually made of tantalum or tantalum oxide, coated on the top and bottom of the aluminum foil. When a voltage is applied across the terminals of the capacitor, the oxide film on the aluminum foil forms an electrical double layer due to the electrolyte. This double layer acts as a dielectric between the positive and negative electrodes and ensures that the capacitor does not conduct any current. The capacitance of the capacitor is determined by the thickness of this oxide film and the area of the electrodes. The UPM1E102MHD1TO capacitor has a number of advantages, including a very low leakage current, low impedance, and stability under varying temperatures. It is also very reliable and has a long life span, making it ideal for many high-demand applications. Its relatively large capacitance for its size also makes it an attractive option for applications where space is at a premium. In conclusion, the UPM1E102MHD1TO is an ideal choice for high voltage applications due to its high stability and extremely low leakage current. Its large capacitance, long life, and reliable operation make it a viable option for many high-demand applications where space is a premium.
