Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, also referred to simply as an electrolytic, is a type of capacitor that uses an aluminum oxide film as its electrolyte, instead of the paper and oil layers found in standard capacitors. This type of capacitor has a much higher capacitance than traditional paper and oil capacitors, and it has the ability to handle much higher voltage levels. The EKZN100ELL182MK16S is an example of an aluminum electrolytic capacitor.

Application Field and Working Principle

Aluminum electrolytic capacitors are widely used in low frequency, filtering, buffer, smoothing, energy storage, coupling, rectifying, and other applications. Generally, these capacitors are used in low-frequency applications such as power supplies, amplifiers, and audio equipment. In high-frequency applications, aluminum electrolytic capacitors are typically used for energy storage and buffering.

The working principle of aluminum electrolytic capacitors is relatively simple. As most capacitors, they act as a device that holds an electric charge. An electrolytic capacitor is composed of two layers. The first layer is an aluminum foil-coated layer (cathode) and the second is a layer made of an oxide film that is used as an insulator (anode). The anode is usually covered in a protective film to prevent short-circuiting.

The charge on the anode is proportional to the applied voltage across the capacitor\'s terminals. Once the applied voltage is removed, the charge will stay on the anode due to its oxide insulation. As the charge slowly dissipates, the voltage across the terminals drops, and the capacitance of the capacitor is reduced. This is why aluminum electrolytic capacitors are said to have a limited shelf life.

The capacitor also has other properties such as temperature coefficient, ESR, and polarization. The temperature coefficient affects the capacitance of the capacitor, that is, its ability to store a charge. The ESR is an important factor as it determines how well the capacitor will dissipate heat. The polarization describes how the capacitor behaves with polarity reversal.

The EKZN100ELL182MK16S aluminum electrolytic capacitor is a small, high-voltage capacitor featuring long life and high-temperature tolerance. It is rated for 50 VDC and has a capacitance of 100 uF. This type of capacitor is typically used in a wide variety of applications such as DC-DC converters, power supplies, power amplifiers, audio systems, and many more.

To conclude, the EKZN100ELL182MK16S is an aluminum electrolytic capacitor rated for 50 VDC and has a capacitance of 100 uF. It is typically used in low-frequency applications such as power supplies, amplifiers, and audio equipment. This type of capacitor has a high capacitance and is able to handle high voltage levels. It also has properties such as a limited shelf life, a temperature coefficient, ESR, and polarization.
