EKY-250ELL331MH15D

Aluminum Electrolytic Capacitors are electronic components that store electrical energy in an electrostatic field. They are widely used across many applications, particularly in the form of electrochemical capacitors that store charge in an electrolyte solution. One of the most common types of aluminum electrolytic capacitors is the EKY-250ELL331MH15D. This capacitor is a type of polarized electrolytic capacitor, meaning that it has positive and negative terminals and can hold a positive or negative charge.The EKY-250ELL331MH15D is typically used in audio circuits, power supplies, and high voltage applications, as it can handle up to a maximum operating voltage of 50 volts. It is also suitable for high frequency applications due to its low equivalent series resistance (ESR). The EKY-250ELL331MH15D has a maximum ripple current rating of 110mA at 120Hz and can store up to 4.3 microfarads (uF) of charge.The working principle for aluminum electrolytic capacitors begins with the electrolyte solution that is composed of dissolved salts and acids inside the capacitor. When a voltage is applied to the terminals of the capacitor, the ions in the electrolyte solution move creating a current of electrical charges. This current flows through the aluminum oxide layer and is stored at the interface between the oxide and aluminum electrode. This stored charge produces an electric field that provides the capacitor with the necessary electrical energy to operate.The aluminum electrolytic capacitor needs to be carefully designed to achieve the desired electrical characteristics. It consists of an anode, cathode, a dielectric of aluminum oxide, and an electrolyte solution to provide the necessary ions for the transfer of electrical current. The anode and cathode are made from aluminium foil and aluminum oxide provides the insulating dielectric layer. The electrolyte is used to allow the necessary ions to move between the anode and cathode.The anode and cathode of an aluminum electrolytic capacitor are both connected to one terminal of the capacitor. The cathode is generally connected to the positive side of the power supply while the anode is connected to the negative side. When a positive voltage is applied to the capacitor, electrons flow towards the cathode causing it to become positively charged. At the same time, anions in the solution move towards the negatively charged anode. This flow of charge in the electrolyte creates an electric field across the capacitor dielectric, which enables the capacitor to store energy.
