Aluminum electrolytic capacitors are electrical components that store electrical energy in an electric field and are made up of two aluminum foils separated by a paper or film. The MAL203137221E3 is an aluminum electrolytic capacitor designed for various applications in which low output noise, no-load characteristics, no-load leakage current, and high reliability are critical. This capacitor features a 105°C lifetime, reliability and a long lifetime of up to 2000 hours at 85°C.

The operating principle of an aluminum electrolytic capacitor is based on a reversible chemical reaction of aluminum foils consisting of aluminum faraday electrodes and an electrolyte. An electric current passes through the electrolyte, creating an electric field across the aluminum foils, which causes a charge to accumulate in the electrolyte. This charge is stored in an electric field generated by the aluminum foil electrodes and the electrolyte. This process is called Faraday\'s law of electrolysis.

The MAL203137221E3 aluminum electrolytic capacitor is mainly used in power supply, low frequency and medium frequency circuits, as well as consumer and communication electronics. It is suitable for applications where low output noise, no-load characteristics, no-load leakage current, and high reliability are important, such as mobile phones, automotive electronics, digital equipment, energy converters, and battery chargers. It is also widely used for lightning protection in various electronic products.

The MAL203137221E3 aluminum electrolytic capacitor features a long lifetime of up to 2000 hours at 85°C, a no –load leakage current of less than 1uA, and a capacity range of 0.47uF to 4.7uF. The capacitor also offers a voltage range of 4V to 100V, a no-load voltage drop of less than 0.3V, and a positive and negative temperature coefficient of +0.05% per °C and −0.05% per °C, respectively. These features ensure a high level of safety and reliability, as well as compatibility with different products.

In conclusion, the MAL203137221E3 aluminum electrolytic capacitor is an efficient and reliable way to store electrical energy in an electric field. It is suitable for many applications and offers features such as low output noise, no-load characteristics, no-load leakage current, and high reliability.
