Aluminum electrolytic capacitors are considered some of the most versatile and reliable capacitor methods available in electrical engineering, and also one of the most common capacitor types. Generally speaking, they are essentially polarized capacitors, whereby the negative terminal is identified by a “-”, and the positive terminal identified by a “+”. The device is composed of a specially-melted aluminum anode foil and an aluminum oxide film, which is then placed and sealed between two layers of insulating layers. Perhaps most importantly, an electrolyte solution such as an alkaline solution or a mixture of water and boric acid is then added to the device.

An aluminum electrolytic capacitor with the model number 860021374004 is a non-polarized, surface-mount device capable of high volumetric efficiency. It has an electrolyte composition of ammonium and zinc carbonate, which gives it a wide range of applications and makes it suitable for wet and dry locations. Its package dimensions are 4.0mm x 6.5mm and it can tolerate part immersion in oil. Additionally, it is highly stable, has a long shelf life, low DC resistance, and a wide temperature operating range. These properties make the 860021374004 a great choice for filtering, bypass, smoothing and decoupling applications in many electronic components.

In terms of its voltage rating, it can handle up to 35 volts DC and its capacitance value range is from 22uF to 680uF. Its rated ESR is 0.036 Ohms and has a rated ripple current of 48mA. Moreover, the 860021374004 is capable of operating at temperatures ranging from -55 to +105 degrees Celsius. This makes it suitable for use in industrial electronic applications, especially those located in areas where temperature fluctuations are common.

The working principle of the 860021374004 aluminum electrolytic capacitor heavily relies on a series of electrochemical reactions that take place inside the device. This begins when the anode foil is immersed in the electrolytic solution and a current is applied between the anode and the cathode. This causes the Aluminum Oxyhydroxide (AlOOH) which is in physical contact with the electrolyte solution, to be oxidized. As the reaction occurs, a capacitance is generated due to the electrolyte acting as the separation medium between the electrodes. The reaction also forms an electrical charge, which is necessary for storage.

Conversely, the capacitor discharges when the current between the electrodes is disrupted. This causes the electrolyte to oxidize the Aluminum Oxyhydroxide, which in turn reverts it back to the its original form. This process releases the charge that previously stored in the device.

In conclusion, aluminum electrolytic capacitors like the 860021374004 are popular and reliable capacitor solutions which can be used in a wide range of applications. Its polarized electrical structure and solid electrolyte composition make it ideal for a variety of projects. Additionally, its wide temperature operating range and long shelf life make it suitable for extended use in harsh environments.
