Working Principle:

The EKYB800ELL821MLN3S aluminum electrolytic capacitors are based on a polarized electrolytic dielectric. This means that the electrodes of the capacitor are made of aluminum and the electrolyte is a solution of water and a soluble salt. When voltage is applied between the electrodes, the electrolyte reacts with the electrodes, creating an electric double layer (EDL) which consists of layers of mobile ions and electrons. This EDL forms a dielectric which increases the electric field strength between the electrodes. This increases the capacitance of the capacitor.

In addition, the electrolyte also helps to filter out unwanted ripple and noise, thereby reducing the ESR of the capacitor. This makes the EKYB800ELL821MLN3S capacitor especially well-suited for applications requiring high ripple currents and/or high voltage.

In summary, the EKYB800ELL821MLN3S aluminum electrolytic capacitor is an important electronic component, which is used in many different applications. Its polarized electrolytic dielectric gives it a high capacitance and low ESR, making it especially suitable for applications requiring high ripple currents and/or high voltage.
