KMH100VS222M30X40T2

Aluminum Electrolytic Capacitors

The KMH100VS222M30X40T2 is a part of the Aluminum Electrolytic Capacitor family, a capacitor with an electrolyte that stores electrical energy as an electrostatic field. It has a cylindrical metalized casing and is polarized (there is an anode and a cathode). The main advantages of this capacitor include high energy density, long life and high capacitance. This capacitor is suitable for various AC and DC applications, such as across-the-line start-up, motor start-up, power factor correction and energy storage.

Application Field

Aluminum electrolytic capacitors are widely used in many industries, for example, in Automotive, Audio, Renewable Energy, Industrial, Defense, and Aerospace applications. The KMH100VS222M30X40T2 is suited for applications that require high energy density and long lifetime such as motor start-up, power factor correction, and energy storage. It is also capable of withstanding high voltage (> 10kV), which makes it suitable for high-power applications.

Working Principle

The working principle of the Aluminum Electrolytic Capacitor is that the anode and cathode are separated by an electrolyte, and voltage applied between the electrodes causes movement of ions in the electrolyte. The ions then form an electric double-layer at the electrode surface, and the capacitance is determined by the size of the electrode, the distance between the electrodes, and the relative permittivity of the electrolyte. The anode is typically aluminum foil, while the cathode is typically a wetted paper or other material. The electrolyte may be a liquid or solid, depending on the specific capacitor type.

At high current levels, an Aluminum Electrolytic Capacitor exhibits an equilibrium behavior known as “self-healing”, in which the capacitor is capable of re-forming its aluminum oxide layer. This is one of the hallmark features of Aluminum Electrolytic Capacitors, which allows them to be used in high current applications where other capacitors (such as ceramic capacitors) may not be suitable. The KMH100VS222M30X40T2 is rated for up to 25A continuous current and 100A surge current.

In addition to this, Aluminum Electrolytic Capacitors are able to store a large amount of energy for their size, and are generally very reliable and robust. They have a very low equivalent series resistance (ESR), which is useful for applications requiring low losses and high power density.

The KMH100VS222M30X40T2 is an ultra-low ESR capacitor with high ripple current and long life capabilities. It has an operating temperature range of -55°C to +105°C, and can withstand up to 100V to 2kV voltage. It also has a high ripple current capability of up to 400%.

In conclusion, the KMH100VS222M30X40T2 is an ideal choice for applications that require high energy density, long life and high capacitance. It is a practical, reliable and robust option for motor start-up, power factor correction, and energy storage applications where high voltage and high current are required.
