Aluminum electrolytic capacitors are useful components in the electrical and electronics industry. The MAL21 series is a range of capacitors which are well known for their performance and reliability. The MAL211837479E3 component is an electrolytic capacitor that has a wide range of applications. This article will discuss the application field and working principle of the MAL211837479E3 aluminum electrolytic capacitor.

The MAL211837479E3 aluminum electrolytic capacitor is designed for high frequency AC circuits and is suitable for use in a variety of power supply circuits. This capacitor is primarily used in signal or electronic equipment and other circuits which need high-frequency ripple currents. Other uses of the MAL211837479E3 include high frequency noise reduction and decoupling applications in DC-DC converters, automotive audio devices, and display devices.

The working principle of the MAL211837479E3 is based on the concept of electrolytic capacitance. The capacitor is constructed with a metalized paper electrode, which is covered with a conductive electrolyte. This electrolyte forms a semi-permeable membrane between the metalized paper and the aluminum foil. When an external voltage is applied to the capacitor, ions from the electrolyte pass through the membrane and deposit on the metalized paper, forming a layer of deposited ions. These deposited ions form an electrostatic field which has a capacitive effect. The amount of capacitance of the capacitor depends on the thickness and area of the deposited layer and the electrolyte used.

The MAL211837479E3 aluminum electrolytic capacitor has a good temperature range and can operate at temperatures up to 85°C without derating. The capacitor also has a good voltage stability and current handling capacity with a rated voltage of up to 35V and a rated current of 6.2A. This capacitor also has high impedance and low equivalent series resistance (ESR), making it suitable for applications with high ripple currents. The MAL211837479E3 has a long life with an operating life of up to 2000 hours at 85°C. This makes it suitable for use in long-term applications.

In conclusion, the MAL211837479E3 aluminum electrolytic capacitor is a robust component that is suitable for a wide range of applications. It has excellent voltage stability, current handling capacity and temperature range and is therefore ideal for high-frequency AC circuits. The capacitor also has a long life and low equivalent series resistance, making it suitable for long-term applications. The working principle of this capacitor is based on the concept of electrolytic capacitance and the amount of capacitance depends on the thickness and area of the deposited layer and the electrolyte used.
