Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used electronic components which are composed of a steel can, anode aluminum foil, dielectric paper, graphite and electrolyte. They can be divided into several types based on different conditions, such as short-term usage capacitances, long-term usage capacitances and polar capacitances.

The Vishay381LX472M025H012 is a high-quality aluminum electrolytic capacitor featuring a low ESR and very low ESR. This device is specifically designed for applications requiring high-frequency ripple current and low ESR characteristics. Its features include wide capacitance range, high ripple current capability, long life expectancy, and wide operating temperature range.

Application Fields

The Vishay381LX472M025H012 capacitor is widely used in applications such as motor control in electric vehicles, switch power supplies, deflection systems in televisions and monitors, mobile handsets, power supplies and inverters, motor power conversion systems, high-frequency switching regulators, and general switching mode power supplies. It can also be used in dielectric circuits and discharge resistors.

Working Principle

The Vishay381LX472M025H012 uses an electrolyte to produce a dielectric field when voltage is applied across its terminals. The electrolyte reacts with the anode and cathode to form a double electric layer. This double electric layer forms an electrical field and it is this electrical field that acts as the dielectric of the capacitor. The polarization of the electrolyte also carries charges from one terminal to the other, forming a current path between the terminals of the capacitor and allowing it to store electrical energy.

When a signal passes through the capacitor, the capacitive effect of the unit causes the capacitance to change with the amount of signal. The signal is not blocked, but the voltage is delayed by the capacitor before it reaches the next stage. This reduces the effect of any interference and prevents damage to other components due to a surge.

The Vishay381LX472M025H012 aluminum electrolytic capacitor is a reliable and robust component that is easy to use with a wide range of applications. It has a long life expectancy and provides consistent performance. It is available in several sizes, and the operating temperature range and high ripple current capability make it suitable for most power applications.
