Aluminum Electrolytic Capacitors are devices that store electrical energy in an electrostatic field. The MAL205756479E3 is one of the many aluminum electrolytic capacitors that have been developed over the years for various applications. This article will discuss the application field and working principle of the MAL205756479E3.

The MAL205756479E3 is a high-performance aluminum electrolytic capacitor. It is ideal for use in applications where reliability, long life, and low bulk capacitance are required. This capacitor is particularly well-suited for power supplies, motor control, and instrumentation circuits. It is also suitable for automotive, industrial, and medical applications.

The MAL205756479E3 is designed to operate at temperatures ranging from -40°C to 125°C. It is constructed with a foil-electrodes construction, which provides enhanced dielectric stability, reliable leakage performance, and low ESR. The capacitor is polarized, meaning that an external voltage must be applied to the electrodes in a specified direction to achieve proper operation.

The working principle of aluminum electrolytic capacitors is relatively simple. A capacitor is composed of two conductive metal plates separated by a dielectric material. When a voltage is applied across the plates, electrons build up on the negative plate and form an electric field. When the electric field is strong enough, a current will flow between the plates and store the energy in the electric field. The strength of this electric field is determined by the capacitance of the device, which is measured in farads (F).

The MAL205756479E3 aluminum electrolytic capacitor has a capacitance of 4.7µF. This means that the device can store a charge of 4.7 x 10-6 coulombs at a given voltage level. The device also has an equivalent series resistance (ESR) of 15.2mΩ and an equivalent series inductance (ESL) of 4.3nH. The ESR and ESL are important parameters that determine the frequency performance of the device.

To ensure reliable operation, the MAL205756479E3 must be rated for the expected operating voltage and environment. The device can withstand a maximum rated voltage of 200V DC. It is important to note that exposing the capacitor to voltages in excess of this rating will result in permanent damage. The device must also be used in a temperature-controlled environment, as temperatures beyond its specified operating range could cause permanent damage.

In summary, the MAL205756479E3 is a high-performance aluminum electrolytic capacitor designed for applications requiring long life and low bulk capacitance. It has a capacitance of 4.7µF, an ESR of 15.2mΩ, and an ESL of 4.3nH. The device must be rated for the expected operating voltage and environment and must not be exposed to temperatures beyond its stated operating range.
