The High-temperature performance makes the LNX2L822MSEKBN suitable for the harsh environment in industrial applications.

The capacitor can be widely used in the field of power electronics, the application includes DC-DC converters, motor drives, inverters, and power supplies. Due to the high temperature stability and Ripple current, the LNX2L822MSEKBN is very suitable for the switch power supply that requires high frequency operation and long- alive stability.

The working principle of the aluminum electrolytic capacitor is relatively simple. The capacitor consists of two electrodes, made of aluminum and a non-conductor material, and a liquid electrolyte filling the space between the two electrodes. The charging of the capacitor is accomplished by storing the charge carriers within the liquid electrolyte. When a voltage is applied across the capacitor, ions move towards the electrode with opposite charge. The number of ions is proportional to the applied voltage. When the electric field strength between the two electrodes reaches a certain value, the current is saturated and the capacitor is charged. When the voltage is reversed or shut off, the capacitor discharges.

The LNX2L822MSEKBN aluminum electrolytic capacitor also features an improved rubber seal for superior environmental resistance. It is suitable for a wide range of temperatures, from -25°C to +125°C. The low impedance of this part makes it suitable for applications requiring high ripple currents.
