IntroductionAluminum Electrolytic Capacitors is a type of capacitor based on two aluminum foils which serve as the electrodes, with an electrolyte, usually a gel, being sandwiched in between them. In UKT1H0R1MDD1TA aluminum electrolytic capacitors, the two aluminum foils are anode and cathode and form a capacitor with a very large capacitance.Application FieldUKT1H0R1MDD1TA aluminum electrolytic capacitors are mainly used in large pulsed power applications. They can deliver capacitance in high voltage up to 4kV with high energy density. Small versions are often used for general electronics, e.g. power supplies, amplifiers and audio equipments.Due to their large capacitance and high energy ratings, UKT1H0R1MDD1TA aluminum electrolytic capacitors are also particularly suitable for use as energy storage devices in mobile devices, such as laptops, smartphones and smart wearables. In battery-powered applications, they can reduce the weight of the device by combining with a battery in an energy management system, and help to reduce power consumption by providing high power bursts.AdvantagesUKT1H0R1MDD1TA aluminum electrolytic capacitors offer superior performance in terms of their wide temperature range, high ripple current rating, long life and superior voltage capability. They are also very low profile and typically can offer a very high capacitance value for their size.Due to their remarkable heat resistance, UKT1H0R1MDD1TA aluminum electrolytic capacitors are also ideal for automotive applications. They can withstand extreme temperatures and certain models are suited for engine’s start-stop mode applications which are exposed to high temperatures and need responsive and reliable power sources.Working PrincipleIn UKT1H0R1MDD1TA aluminum electrolytic capacitors, the two aluminum foils are surrounded by a pressure-sensitive polymer foil and an electrolyte which is soaked in the polymer. When a voltage is applied, the electrolyte reacts with the aluminum foils producing ions which are attracted to the positive or negative foil. This forms an electric field between the two foils and this creates a charge which is stored in the capacitor.The two aluminum foils are held apart by a separator and thin aluminum oxide layer which acts as an insulation layer. The separator is also made of a pressure-sensitive polymer which contracts when the voltage is applied, increasing the capacitance.ConclusionUKT1H0R1MDD1TA aluminum electrolytic capacitors are extremely versatile and are used in a wide range of applications. They can offer high capacitance for their size and their wide temperature range makes them ideal for automotive applications. They can also provide high power bursts when used as energy storage devices in mobile devices. The working principle of these capacitors is based on the reaction between two aluminum foils and an electrolyte which forms an electric field when a voltage is applied.
