Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is an electrical component used to store an electrical charge for short or long periods of time. It is made of two aluminum foil plates, with an electrolyte in between. When a voltage is applied to the capacitor, the electric field causes ions to move from the negative plate to the positive plate, resulting in a charge separation and the capacitance of the capacitor. The 420USH1000MEFC35X50 application field and working principle describes the type of capacitor and how it works in various applications. The 420USH1000MEFC35X50 is a tantalum-aluminum-titanium electrolytic capacitor. It has a maximum working voltage of 50V and a rated capacitance of 1000μF. Its operating temperature range is -55 - +105°C and its rated ripple current is 420mA at 100KHz at 105°C. This capacitor is typically used in automotive applications where higher temperature and higher ripple current capabilities are needed.To better understand how a capacitor works, consider a single capacitor in an open circuit. When a voltage is applied to the capacitor, it will start to charge up due to the presence of the electric field. As the capacitor charges, a buildup of charge on the plates, also known as an electric field, is created which creates an opposing force to the applied voltage. This creates the capacitance of the capacitor that is measured in farads. The capacitance of a capacitor is also determined by its structure. With the 420USH1000MEFC35X50 capacitor, the construction consists of aluminum plates with a non-conductive oxide layer and an electrolyte between them. As electric current flows through the capacitor, an oxidation reaction, mediated by electrolyte, creates a thin, high-resistance oxide layer that stores the charge. This layer acts as an insulator and prevents any more current flowing into the capacitor. The capacitance of a capacitor can be greatly increased by increasing the amount of surface area between the plates or by using an electrolyte with a higher concentration of ions. In the case of the 420USH1000MEFC35X50, it utilizes a tantalum-aluminum-titanium electrolyte that has a higher concentration of ions compared to traditional aluminum electrolytes, resulting in higher capacitance and a higher ripple current rating. The 420USH1000MEFC35X50 capacitor is designed for use in automotive applications, such as power supplies for car stereo systems, power seats, and other automotive electronics. It is also suitable for a variety of other applications, including lighting, power, electronic signal processing, audio, and speech circuits, as well as computers and telecom applications. Due to its high ripple current rating and temperature range, it is an ideal choice for applications that require stable power delivery with a high level of reliability. In conclusion, the 420USH1000MEFC35X50 capacitor is a high-performance aluminum electrolytic capacitor that is optimized for automotive applications. It features a high capacitance and a high ripple current rating, as well as a wide operating temperature range. It is a reliable and robust capacitor that is suitable for a variety of power delivery and electronic signal processing applications.
