KMG16VB332M12X25LL

Aluminum electrolytic capacitors are electronic components composed of two aluminum plates, a separator paper soaked in electrolyte, and a can. An anode and a cathode are formed by oxidizing one Aluminum film surface, and then a dielectric oxide film is formed on the surface of the Aluminum film. The application field and working principle of KMG16VB332M12X25LL are introduced here.

Application Field

By nature, aluminum electrolytic capacitors are polar capacitors. Due to this polar nature, it is very sensitive to reverse voltage, and the capacitance and leakage current value vary greatly with the change of voltage. Therefore, it is extremely important to design with good environmental conditions when using Aluminum electrolytic capacitors. KMG16VB332M12X25LL capacitors are commonly used in the low, medium and high frequency electronic equipment, such as filter circuits, tuning circuits, coupling capacitors, etc., in order to reduce harmonic distortion. KMG16VB332M12X25LL capacitors are recommended for applications that require high capacitance and long life.

Working Principle

Aluminum electrolytic capacitors are electronic components composed of two aluminum plates, a separator paper soaked in electrolyte, and a can. An anode and a cathode are formed by oxidizing one Aluminum film surface, and then a dielectric oxide film is formed on the surface of the Aluminum film. When an alternating current is applied, electrical charges are accumulated on the two metal plates by EDLC (electro–double-layer capacitor). The electrical charges are balanced when the applied voltage is removed, thereby preventing the capacitor from being discharged. The dielectric has the property of accumulating electrical charges, and the equivalent series resistance (ESR) of the capacitor is very low, which is beneficial for the application of high frequency power. Moreover, due to the specific geometry of the electrolyte and the dielectric, the relaxation time (time-constant) resulting from the internal electrical energy storage capacity is very long, realizing high reliability of Aluminum electrolytic capacitors.

In summary, KMG16VB332M12X25LL belongs to the Aluminum electrolytic capacitors, usually applied in low, medium and high frequency electronic circuits, with large capacitance, low ESR, long life span and suitable temperature coefficient.
