Aluminum Electrolytic Capacitors and the MALREKB00KL322SG0K

Aluminum electrolytic capacitors are a type of capacitor that utilizes aluminum foil for its two electrodes, and which is filled with an electrolyte. The most common example of an electrolytic capacitor that you are likely to find is the MALREKB00KL322SG0K.These capacitors are used in a variety of applications such as power supply filtering, decoupling, and other more specific tasks. They not only provide high levels of capacitance, but are also extremely compact in size and provide excellent electrical characteristics and stability.This type of capacitor is used in the types of devices that require high voltage and high capacitance, as well as for low frequency applications. They are popular in industry and provide excellent results for a wide variety of applications.

Working Principle

The working principle of aluminum electrolytic capacitors is one of self-healing. As the current passes through the capacitor, the ions in the electrolyte are attracted to the surface of the capacitor\'s electrodes and then repulsed by the reverse polarity, creating a spark. This spark causes the aluminum of the capacitor\'s electrodes to oxidize, and as the aluminum is consumed, the liquid electrolyte is effectively drawn up and over the new oxide barrier that is created.This action creates a new barrier between the positive and negative surfaces of the capacitor, and this new barrier is what stores the capacitance that is needed to create the electric field. The capacitance is then able to be used in applications where it is needed, and the aluminum electrolytic capacitor is able to work effectively due to this self-healing action.

Components

Aluminum electrolytic capacitors are composed of several components, including the aluminum foil, which is used as the anode, and the electrolyte, which serves as the cathode. The amount of charge stored in a capacitor is determined by the size of the plates, as well as the dielectric material that separates them.The dielectric can be a number of materials, but it is commonly made from paper, polyethylene, wax, or teflon. This material increases the capacitance of the capacitor, allowing it to store more charge, and it also affects the maximum voltage that can be applied to the device.
