Due to its long life and high current capacity, the MAL213431478E3 is also suitable for applications where high reliability and long service life are required. These include automotive, medical and industrial applications. The capacitor’s wide temperature range of -55°C to +125°C makes it suitable for use in environments with extreme temperature changes.

Working Principle:

The MAL213431478E3 aluminum electrolytic capacitor consists of two pouches: an anode and a cathode. The cathode is filled with an electrolyte solution and the anode is embedded with a dielectric layer. The metal anode is then connected to the outside of the anode pouch, while the metal cathode is connected to the outside of the cathode pouch. This connection is completed through an electrolyte solution which passes through the anode/cathode interface.

When a voltage is applied across the anode and the cathode, electrons are attracted to the anode and the positive ions in the electrolyte are attracted to the cathode. This causes a current to flow through the capacitor, which results in the formation of an electric field between the two pouches. This electric field stores energy, which is then released when the voltage is removed.

The MAL213431478E3 capacitor is designed to operate in DC voltage, and it is also protected against reverse-polarity and overvoltage due to its double end-terminal construction. This means that the capacitor can operate safely in applications with different voltage levels. Furthermore, the lifetime of this capacitor can reach up to 10,000 hours, which is significantly longer than standard aluminum electrolytic capacitors.

In conclusion, the MAL213431478E3 aluminum electrolytic capacitor is suitable for use in many different application fields, including power electronics, power supplies and motor drives. It is designed to last up to 10,000 hours, which makes it ideal for applications requiring long service life and high reliability. Moreover, it is protected against reverse-polarity and overvoltage thanks to its double end-terminal construction.
