Aluminum Electrolytic Capacitors – EKY-500ELL271MK15S Application Field and Working Principle

Aluminum electrolytic capacitors, also known as aluminum capacitors or electric double-layer capacitors, are electric components used to store electricity and enable current flow in electric and electronic circuits. Due to their long life and high power retention, aluminum electrolytic capacitors are used in many different applications including computing, telecommunications, automotive, military, and audio/video equipment. The EKY-500ELL271MK15S is a special type of aluminum electrolytic capacitor rated for 15volts, with a capacity of 2700μF, and a maximum operating temperature of 105°C.

Composition and Structure of EKY-500ELL271MK15S Aluminum Electrolytic Capacitor

The EKY-500ELL271MK15S is composed of an anode and a cathode, separated by an electrolyte. The anode and cathode are typically aluminum foil and paper impregnated with an electrolyte, while the electrolyte is a solution of boric acid, ethanol, and water. The anode is usually etched or electro-deposited with a thin layer of oxide which acts as a dielectric. In addition, a layer of insulation covers each of the anode and cathode to prevent electric charge leaks, and a terminal seal is used to connect the anode and cathode to external circuits.

Applications and Operating Principles of the EKY-500ELL271MK15S

The EKY-500ELL271MK15S is an ideal choice for applications requiring pulse and surge protection, such as voltage regulator modules, automotive lighting systems, LCD displays, and microcontrollers. This type of aluminum electrolytic capacitor has excellent capacitance and high working voltages and thus offers superior protection from potential damage due to voltage and current fluctuations. The operating principle of the EKY-500ELL271MK15S is based on the application of a voltage difference between the two electrodes, resulting in a current flow between them. This current flow is proportional to the voltage difference and is limited by the resistance of the electrolyte. The electric field generated by the applied voltage causes electrolyte ions to migrate and accumulate near the etched aluminum foil, forming an electric double layer and resulting in the addition of capacitance. The total capacitance is a combination of the capacitance of the electric double layer, the capacitance of the oxide layer of the aluminum foil, and the static capacitance of the electrolyte.

Other Characteristics of the EKY-500ELL271MK15S

The EKY-500ELL271MK15S offers superior performance in a wide range of temperature and environments, withstands extreme temperatures (of up to 105°C), and features high ripple current capability, very low ESR, and long-term stability. This aluminum electrolytic capacitor is also resistant to electrical noise, vibration and shock, and its internal construction prevents short-circuiting and damage from solvents.The EKY-500ELL271MK15S is designed to offer reliable performance in various types of electronic devices, making it ideal for those applications that require long-term stability. Furthermore, its voltage rating, capacitance range, small volume, and low price make the EKY-500ELL271MK15S an ideal choice for a variety of applications.
