Aluminum electrolytic capacitors are a type of specialized capacitor mainly used for high-frequency filtering. They are used in various types of electronics applications and come in many shapes, sizes and ratings. One type of aluminum electrolytic capacitor is the ALS70A133QT500, which is specifically designed for use in high-temperature applications. The ALS70A133QT500 capacitor is a radial lead mount, aluminum electrolytic capacitor with a capacitance value of 70μF, voltage rating of 250V, tolerance of +80/-20%, and a standard series temperature rating of -55°C~+105°C.

The construction of an aluminum electrolytic capacitor consists of a layer of aluminum foil acting as the anode, an electrolyte unique to each manufacturer, and an outer layer of aluminum foil or aluminum oxide acting as the dielectric and a cathode. The anode and cathode of an aluminum electrolytic capacitor are separated by a layer of paper or plastic film called the HydrogenGap™ layer, which is used to minimize the rate of hydrogen buildup within the capacitor. As the capacitor is charged, the electric field causes the anode to corrode and a thin, insulating layer of aluminum oxide is formed, effectively storing the electric charge until released. This layer of oxide is the same material used in integrated circuits and is responsible for both the high capacitance, as well as its high temperature capabilities.

High temperature applications require that the capacitor be able to withstand greater electrical stress than the regular aluminum electrolytic capacitor. The ALS70A133QT500 is designed with this in mind and uses an improved dielectric oxide to increase the temperature rating to +135°C. This increased temperature rating allows the capacitor to be used in applications like power supplies and inverters, which produce more heat than a typical capacitor can withstand.

The combination of its high capacitance, voltage, and temperature ratings make the ALS70A133QT500 an ideal choice for many different high-temperature applications. In addition, its radial lead mount construction allows it to be easily installed into tight spaces, making it a great choice for those who need to use it in confined areas. With its reliable performance and long-term stability, the ALS70A133QT500 aluminum electrolytic capacitor is sure to be a top choice for those applications able to take advantage of its capabilities.
