Aluminum Electrolytic capacitors are widely used in the field of electronics due to their high charge and energy storage capacities and their low cost. They are particularly helpful in situations where large amounts of capacitance are needed for a relatively short period of time. The KY35VB122M12X30LL capacitor is designed as a low-ESR device, which allows for very high ripple currents at moderate temperatures. This makes the device particularly suitable for AC/DC rectification and filtering applications.

Application Field

The KY35VB122M12X30LL capacitor is designed to be an excellent choice for applications that require low-impedance power filtering. This would include line-frequency power-supply applications, invertor voltage smoothing, and AC or DC motor controls, among others. The KY35VB122M12X30LL capacitor may also be useful in applications that require very low ESR, such as in full-wave bridge rectifier circuits, DC-DC converters, or DC/AC inverter circuits.

Working Principle

The KY35VB122M12X30LL capacitor is an aluminum electrolytic capacitor. This type of capacitor is composed of two plates of aluminum separated by a dielectric layer, typically made of paper or aluminum oxide film. The layers are soaked in an electrolyte solution. When a voltage is applied, one plate acts as the anode, and the other acts as a cathode, creating an electric field across the layers. This creates an electric dipole and allows the capacitor to store energy.

When current passes through the capacitor, the electric field causes a displacement of charges, resulting in a change in voltage across the plates. This allows the capacitor to act as a filter, blocking DC components of the signal and allowing only small AC components to pass through. By varying the capacitance, the rate at which the voltage changes across the plates can be altered, which allows the capacitor to store energy for a longer or shorter period of time.
