Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor (ALC) is an electrochemical component that works by using an electrolyte and a solid aluminum oxide film that acts as a cathode. This combination helps create a double-layer capacitor with a very high capacitance/volume ratio and a low equivalent series resistance (ESR). Although these types of capacitors can be used in almost any application, ALCs are mainly used in applications where ripple or noise current reduction is needed due to their high capacitance values per unit volume.

MAL205758151E3 application field and working principle

The MAL205758151E3 is an aluminum electrochemical capacitor specifically designed for use in high voltage and high temperature applications. This ALC is rated for a working voltage of 550VDC and a working temperature range of -40 to 125 °C. Moreover, it has an extended life of up to 2000 hours at 200% rated voltage and 125°C. Additionally, the ripple current capabilities of this ALC are quite impressive, as it is rated to withstand up to 32.2A @ 100KHz. The design contains double-layer capacitance to give it a low equivalent series resistance (ESR) and a long service life.

The MAL205758151E3 is particularly well-suited for switch mode power supplies (SMPS) due to its high ripple current capabilities. This allows it to be used in power inverters, LED drivers, uninterruptible power supplies (UPS), and AC/DC applications. Additionally, it can also be used in automotive applications such as power steering and electric fuel pumps. Other applications where the MAL205758151E3 can be used include UPS systems, electric vehicle power supply systems, motor drives, frequency converters, and lamp ballasts.

The technology behind the MAL205758151E3 is an anode composed of pure aluminum foil which acts as an electrolyte. This, in conjunction with a cathode made from solid aluminum oxide film, forms an electrochemical capacitor. The anode-cathode junction provides increased capacitance and a low ESR, making it well suited for high ripple current applications.

The advantages of the MAL205758151E3 over other types of capacitors include its higher capacitance/voltage value, long life, and extremely low ESR. It also has excellent reliability and stability in high voltage and temperature applications. Additionally, its height of only 8.1mm allows for easy installation in switch mode power supplies, making it a viable solution for applications where size and space are limited.

In summary, the MAL205758151E3 is an aluminum electrochemical capacitor designed specifically for the purpose of providing high voltage, high ripple current, and extended life in a wide range of applications. Its high capacitance/voltage value and low ESR make it well suited for power inverters, LED drivers, and automotive applications where space is limited.
