Aluminum Electrolytic Capacitors are a type of electrolytic capacitors mainly composed of an aluminum oxide layer formed on the surface of aluminum foil and a non-solid electrolyte. They have high voltage, large capacity, small volume, wide operating temperature range, long life and good self-healing. Because of these advantages, they are widely used in various electronic circuits. Among them, the LXZ6.3VB682M16X25LL is a type of aluminum electrolytic capacitor, which will be discussed in detail in this article.LXZ6.3VB682M16X25LL aluminum electrolytic capacitor is a cylindrical surface-mount device made of aluminum and equipped with an electrolyte. Its rated voltage is 6.3 VDC, capacitance is 0.682 μF and working temperature is -40℃ to +125℃. The entire component measures 16mm in diameter and 25mm in height.Such aluminum electrolytic capacitors are mainly used in various electronic circuits that require large capacitance, pressure, voltage, temperature, and other conditions, such as power supplies, timing circuits, and video circuits. They can also be used in-circuit applications such as power amplifiers, electric motors, and UPS systems, and in military systems such as communication and navigation.The working principle of an aluminum electrolytic capacitor is that when the capacitor is charged, the anode surface of the aluminum foil spontaneously forms an oxide film to isolate the two layers, and the non-solid electrolyte is inserted into the oxide film to form an electric double-layer. During this process, an electric field is formed, resulting in a reduction in the capacitor’s internal electric resistance. The energy required for the charge-discharge of the capacitor is supplied by the aluminum oxide layer and the dielectric layer formed between them.When the capacitor is in a discharged state, the oxide layer becomes thinner due to the large current, which causes the static capacitance to decrease. This results in a loss of blocking power and a decrease in voltage breakdown due to the decrease in the thickness of the dielectric layer. If the internal pressure of the capacitor increases, it may even rupture or explode. Therefore, it is necessary to use a corresponding fuse and protection circuit to protect the capacitor from over-current and over-voltage.In conclusion, the LXZ6.3VB682M16X25LL aluminum electrolytic capacitor is a type of capacitor with high voltage, capacity, temperature range, and self-healing properties, making it suitable for use in various electronic circuits. Its working principle is to use an oxide layer on the anode surface and an electric double-layer produced by the non-solid electrolyte to reduce internal electric resistance and store charge. Nevertheless, over-current and over-voltage need to be controlled in order to avoid damage to the capacitor.
