Aluminum electrolytic capacitors are an important type of passive electrical component. They are widely used in electronic circuits for filtering and buffering, for their high capacitance, low leakage current and high working voltage. The UVZ1C682MHD is a common type of aluminum electrolytic capacitor. This article will discuss its application fields and working principle.

The UVZ1C682MHD aluminum electrolytic capacitor is primarily used in power supplies and voltage stabilizers, due to its high dielectric strength and low impedance characteristics. This makes it especially suitable for high voltage circuit applications. It is also used in the output stage of audio power amplifiers, or as a bypass capacitor in DC-DC converters. The general specifications of the UVZ1C682MHD are as follows: rated voltage of 25V, an ESR of 0.4 ohms, and an impedance score of 11.

The working principle of the UVZ1C682MHD aluminum electrolytic capacitor lies in its construction. It is an electrochemical device, composed of an anode (positive electrode), a dielectric (insulating layer), a cathode (negative electrode) and an electrolyte. When it is connected to a voltage source, the positive and negative charges will accumulate on the anode and cathode respectively, which creates an electric field. the electric field acts on the insulating layer, causing ions from the electrolyte to move towards the anode, thus forming a layer of conducting material between the two electrodes, which is known as the "depolarizer". This allows electrical current to flow between the anode and cathode, leading to a capacitance effect.

The capacitance of the UVZ1C682MHD aluminum electrolytic capacitor is dependent on the size of its construction, as well as the type and concentration of electrolyte used. The capacitance value can be adjusted by altering these parameters. Other factors that affect the capacitance include the temperature of the operating environment and the voltage applied to the capacitor. The capacitance of the UVZ1C682MHD is low compared to other types of capacitors, however, due to its low ESR, it has a higher tolerance to heat and high voltage, making it suitable for applications that require stability and reliability.

In conclusion, the UVZ1C682MHD aluminum electrolytic capacitor is a common type of capacitor that has a wide range of applications in power supplies, voltage stabilizers, audio power amplifiers and DC-DC converters. It has a low capacitance value, yet its low ESR and high voltage capabilities offer significant advantages over other types of capacitors. This makes it a reliable and versatile choice for many applications.
