Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in electronics due to their wide frequency range, high capacitance, and low loss. They are permanent, and must be replaced if they fail. They are available in both radial and axial configurations.

The UKA1C331MPD is a radial aluminum electrolytic capacitor with a rated voltage of 330 VDC and a capacitance of 200uF. It has been designed for applications where high capacitance, long life, high reliability, and high ripple current are required.

Application Field

The UKA1C331MPD is used in a variety of applications including power supply systems, AC adapters, and other high voltage or current applications. It is particularly useful for applications where high ripple current is required. It is also used as a decoupling capacitor in oscillator circuits, and as a rectifier filter capacitor in switching power supplies.

Working Principle

The working principle of an aluminum electrolytic capacitor is based on its structure. It consists of two aluminum foil layers separated from each other by a dielectric layer. The anode foil is coated with an electrically conductive layer called an anode gel, and the cathode foil is insulated and non-conductive. When a voltage is applied to the capacitor, an electric field is created across the anode gel and the dielectric layer, which increases the number of ions in the gel. This increases the total capacitance of the capacitor. It also causes an increase in the electrical current flowing through the capacitor, as well as an increased polarization of the dielectric layer.

The capacitance of an aluminum electrolytic capacitor is determined by the amount of aluminum in the foil layers and the dielectric layer, as well as the surface area of the foil layers. The amount of aluminum in the foil layers also determines the dissipation factor, which measures the amount of electrical current lost in the capacitor.

The UKA1C331MPD is designed to offer high capacitance, long life, and high reliability. It is rated for operation at temperatures up to 105°C and for ripple currents up to 55mA. It features a low dissipation factor and is designed for low impedance and high dielectric strength. It is also resistant to humidity, vibration and shock, making it ideal for use in demanding applications.

The UKA1C331MPD is an excellent choice for applications requiring a high capacitance, long life, and high reliability. It is a reliable and cost-effective capacitor that has many advantages over other aluminum electrolytic capacitors.
