Aluminum electrolytic capacitors are passive electronic components whose primary function is to store electric charges and maintain a possible difference in potential. 687SMH016M is the model of a type of aluminum electrolytic capacitors. It is a non-polarized, radial lead aluminum electrolytic capacitor with a radial lead and a screw terminal. 687SMH016M has a non-solid electrolyte and a conductive polymer cathode. The capacitor is made of an aluminum case, anode foil, separator, electrical insulation, etc.The application field of 687SMH016M is quite wide. It is widely used in a variety of circuits, such as filtering, decoupling, buffering and energy storage. For example, it can be used in the Audio device, high-frequency transmission equipment, AC motor and rectifier, power semiconductor drive circuits and DC control circuits in Medical field. Moreover, it can also be used in electronic instruments, telecommunications and security systems.The working principle of 687SMH016M is based on the principles of electrochemistry. In an aluminum electrolytic capacitor, a layer of oxide layer is formed on the surface of the Aluminum anode, resulting in the formation of two electric fields between the two poles, the anode and the cathode. When a voltage is applied to the capacitor, an electric field is generated between two layers of aluminum oxide. This field attracts and repels the opposite charges on the two ends of the capacitor, creating a steady flow of electrons between two plates of aluminum oxide, thus forming an electrostatic field.When the anode acts as the positive pole, electrical charges are attracted to the anode and the current flows. Similarly, when the cathode acts as the negative pole, electrical charges are repelled from the anode and the current flows in the opposite direction. In this way, an electric charge is stored in the capacitor.The dielectric material between the two plates of the aluminum electrolytic capacitor controls the potential of the electric field generated inside the capacitor. In 687SMH016M the dielectric material is a non-solid electrolyte. This electrolyte allows the anode to absorb and store electrons until the capacitor is fully charged. The amount of charge stored in the capacitor is proportional to the applied voltage, and the capacitance of the 687SMH016M can be changed to suit different applications.Finally, after a potential difference is established between the two plates, an electric field is maintained in the capacitor. This field stores the electric charge in the capacitor until it is discharged. The charge stored in the capacitor is then released to the cathode, and the capacitor is discharged. In short, 687SMH016M is an Aluminum Electrolytic Capacitor. It has wide range of application field and its working principle is based on electrochemistry. The dielectric material between the two plates of the aluminum electrolytic capacitor controls the potential of the electric field generated inside the capacitor. This capacitor has a non-solid electrolyte and a conductive polymer cathode, and its capacitance can be changed to suit different applications.
