Aluminum Electrolytic Capacitors are solid, reliable components used in a wide range of applications. The ALS80H472QH500 is a high quality Aluminum Electrolytic Capacitor, and is an ideal choice for use in many electronics projects. As such, it is useful to understand the characteristics of this component and its field of application.The ALS80H472QH500 is distinguished by its significant capacitance of 4700 microfarads (4700µF). This typical value is specified with a nominal or working voltage of 500 Volts DC. It is available with a tolerance of ±20% and a rated temperature of 105°C. The case is made from aluminium, with a waterproof seal preventing leakage. The electrode lead wires are of 40 mm in length and 1.2 mm in diameter.The ALS80H472QH500 is designed for use in a broad range of industrial or consumer circuit applications. Commonly, it is used as a filter or decoupling to filter out interference and ripple, and for snubber circuits. The high capacitance gives it a low internal impedance, so it is also suitable for input and output smoothing applications with DC motors. It has a wide range of uses in audio and high voltage circuit applications, and is also suitable for use in amplifier circuits or in power factor correction.The working principle of this Aluminum Electrolytic Capacitor is based on the traditional electrolyte capacitor design. The main characteristic of this component is that it is polarised, meaning that it will not function correctly when the voltage is applied in the wrong direction. This means that the positive lead must always be connected to the product with a higher voltage than the negative lead.When the ALS80H472QH500 is correctly mounted, its cylindrical aluminum case acts as one of its two electrodes. The opposite electrode is formed by a layer of aluminum oxide on the electrolyte material, which can be found inside the sealed case. This effect is known as anodic oxidation, and it forms the foundation of the capacitor. The two electrodes are connected within the case by two lead wires, and are insulated from each other.When a voltage is applied across the two electrodes, the current will flow and the capacitor will begin to charge. The electrolyte material will be polarized and form a dielectric between the two electrodes, allowing for a build-up of electrical energy. This stored energy can then be used during a period of peak demand.The capacitor is discharged when the voltage is no longer applied. The internal current will then quickly return to a low level at which point the electrolyte material will form a dielectric again and allow for a further build-up of electrical energy. This process will continue as long as power is applied to the capacitor.The ALS80H472QH500 is an exceptional Aluminum Electrolytic Capacitor, and is ideally suited for a wide range of applications. Its high capacity and durable case make it perfect for a variety of consumer and industrial applications. Moreover, the highly reliable characteristics of the capacitor are ideal for both input and output applications and protection against overloads.
