Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor that is part of a larger family of electrolytic capacitors. These capacitors contain an anode made of aluminum and a cathode where two rolls of aluminum foil are anodized along with a non-conducting paper separator in between the two rolls. The anode and cathode are normally immersed in an electrolytic fluid that acts as an insulating material. These capacitors have several advantages such as long life, high capacitance to volume ratio and high ripple current as compared to other types of capacitors.

The MAL211818471E3 aluminum electrolytic capacitor is 11 mm in diameter and 18 mm in length. It is a radial leaded and sits directly onto a PC board. It has a capacitance of 470 μF at 25 degrees Celsius and a working voltage of 250VDC/50VAC. It also has a voltage drop of 30 and a maximum ripple current of 3955. The MAL211818471E3 has a wide range of applications and can be used in power supplies, medical equipment, instrumentation, and audio/video equipment. It is also a commonly used cap in the automotive industry, particularly in power and battery applications.

The working principle of the MAL211818471E3 aluminum electrolytic capacitor is based on the concept of storing electrical energy in the form of an electric field within two conductive plates. The two conductive plates are separated by a dielectric material, which is an insulator. The electrical energy is imparted onto the plates via an electric charge. This charge causes a positive electrical field to form above the anode and a negative electrical field below the cathode. When the capacitor is connected to an electrical circuit, current is derived from the electric field stored in the capacitor. As current passes through the capacitor, the capacitor\'s voltage is increased and decreases again as the electrical charge dissipates.

The large capacitance of the MAL211818471E3 aluminum electrolytic capacitor makes it ideal for use in applications where large amounts of voltage and current must be stored. Its low ESR (equivalent series resistance), low leakage current, and large temperature range makes it suitable for applications involving a wide range of temperatures and voltages. Its long life and good humidity resistance makes it especially suitable for use in high humidity and temperature applications such as those found in medical and automotive applications.

In conclusion, the MAL211818471E3 aluminum electrolytic capacitor is an ideal choice for a variety of applications such as power supplies, medical equipment, instrumentation, and audio/video equipment. It is an efficient capacitor with a wide range of temperature and voltage tolerances and also a high capacitance to volume ratio. Its low ESR, low leakage current, and long life makes it suitable for a wide range of applications, especially those involving high levels of humidity and temperature.
