Aluminum Electrolytic Capacitors are widely used in applications that require high capacitance reactance from low cost components. MAL201376478E3 is an aluminum electrolytic capacitor from Vishay Intertechnology, Inc. It has long life characteristics and is a cylindrical type, with an operating temperature range of -55C to +105C. This capacitor has the advantage of high capacitance, low ESR, and high ripple current.

Capacitor Materials

The MAL201376478E3 capacitor is composed of three main components. The aluminum anode is an aluminum foil coated with a layer of oxide film. It is a highly porous dielectric material with good electrical conductivity. The separator is a paper type and it serves as a double-layer dielectric and provides electrical insulation. The cathode is an aluminum foil rolled into a cylinder shape, so as to provide a large surface area for the electrolyte to come in contact with.

Capacitor Coil Electrolyte

The electrolyte used in the capacitor is a weakly acid or alkaline solution that serves as the conductor between the anode and cathode. This electrolyte carries the charge from one plate to another, thus forming a capacitor. Depending on the application, the electrolyte can be of either polyester type or polycarbonate type.

Working Principle

The working principle of the capacitor is based on electrochemical principles. When the plates of the capacitor are charged, free electrons move towards the cathode plate and ions move towards the anode plate. The distance between the plates determines the capacitance of the capacitor. A large capacitance is achieved when the plates are far from one another.

When the capacitor is connected to an alternated alternating current (AC), the capacitor acts as a combination of a resistor and an inductor, allowing current to flow and storing energy in the form of electrical charge. When the current of the AC is decreasing, the capacitor is charged with more and more energy, while when the current of the AC is increasing, the capacitor is discharged and sends the energy back into the system. Repeating this cycle will produce a continuous current flow.

Applications of MAL201376478E3

The MAL201376478E3 is mainly used as an energy storage device in AC power circuits. It is used to reduce electrical noise and suppress high-frequency interference in the circuit.
