Aluminum electrolytic capacitors are widely used in many fields, particularly in modern electronics. KMQ200VS391M22X25T2 is an aluminum electrolytic capacitor type, which has its specific application fields and working principles.Application FieldAs a popular part in the electronic industry, KMQ200VS391M22X25T2 aluminum electrolytic capacitor mainly used in the DIY area, such as DC power supply, motor drive, audio filtering, etc. Among them, the main application areas of KMQ200VS391M22X25T2 are electronic servo systems, stabilizers, PFC circuits, magnetic amplifiers, power gyroscope units and medical power amplifiers. In addition, this kind of aluminum electrolytic capacitor can also be used in electronic product development, switch mode power supply power systems, various level-sensitive circuits, frequency conversion thyratron phase modulation, communication systems and automotive electronics.Working PrincipleThe KMQ200VS391M22X25T2 type aluminum electrolytic capacitor is composed of an anode of aluminum foil, a cathode of aluminum foil coated with a layer of oxide film and a separator composed of a anion perm rated paper soaked in electrolyte. The working principle of it is that the anode and cathode are alternately connected by positive and negative electrodes of the external lead, and the two are separated by the dielectric. When a AC voltage or direct current voltage is applied to this pair of electrodes through a power supply, an electric field is generated in the capacitor due to the differential of potential and the dielectric constant of the dielectric. The electric energy stored in the capacitor can appear when the power supply is off.In addition, a third characteristic of the KMQ200VS391M22X25T2 aluminum electrolytic capacitor is its high volumetric efficiency. The main reason of this is due to its very small height compared with other capacitor types. This allows high value capacitors in a smaller physical size, and thus with minimal space requirements. The same applies when compared with the volume efficiency of other types of capacitors, so the volumetric efficiency of the KMQ200VS391M22X25T2 type should be considered.ConclusionIn summary, KMQ200VS391M22X25T2 aluminum electrolytic capacitor has its specific application field and working principle. It is mainly used in the DIY area, such as DC power supply, motor drive, audio filtering, electronic servo systems, stabilizers, PFC circuits, magnetic amplifiers, and power gyroscope units. Its working principle is that when a AC voltage or direct current voltage is applied to this pair of electrodes, an electric field is generated in the capacitor due to the differential of potential and the dielectric constant of the dielectric. It also has high volumetric efficiency due to its very small height compared with other capacitor types.
