Electric Double Layer Capacitors (EDLC), Supercapacitors
DCK-3R3E224U-E is a type of electric double layer capacitors (EDLC) and supercapacitors. EDLCs are energy storage devices that allow fast charge and discharge for a highly reliable power source. Supercapacitors are energy storage devices that use double-layer capacitance to store a large amount of energy.
Application Fields for DCK-3R3E224U-E
DCK-3R3E224U-E capacitors have a range of application fields, including automotive, consumer electronics, and industrial applications. Some of the most common applications are in automotive engines and starter motors, consumer electronics like smartphones and tablets, and industrial equipment like backup power supplies.
The low equivalent series resistance (ESR) of the DCK-3R3E224U-E capacitors makes them ideal for use in automotive engines and starter motors. The high energy density of the capacitors leads to longer life for the engine, making them a great choice for engines that require frequent starts and stops. The DCK-3R3E224U-E capacitors are also well-suited to consumer electronics applications, providing high peak currents that are necessary for powering devices such as smartphones and tablets. For industrial applications, the DCK-3R3E224U-E capacitors are especially popular for their low ESR and high energy density, making them an excellent choice for backup power supplies or other equipment requiring instantaneous energy.
Working Principle of DCK-3R3E224U-E
The working principle of the DCK-3R3E224U-E capacitor is based on the phenomenon known as double-layer capacitance. A double-layer capacitor is composed of two electrodes separated by a separator. When the electrodes are charged, a thin layer of electrical charge is held between the two electrodes, known as the double layer. This double-layer is responsible for storing energy in the form of an electric field.
DCK-3R3E224U-E capacitors use a dielectric electrolyte to charge and discharge the double-layer. The dielectric electrolyte is composed of two fluids that are mixed together in order to create ionic bonds between the charged particles. This allows the capacitors to charge and discharge quickly, providing a high level of power delivery.
DCK-3R3E224U-E capacitors are designed to provide high energy delivery and long life. The double-layer structure and the use of electrolytes create a high level of durability. Additionally, the high energy density of the capacitors allow them to store more energy than traditional batteries, and the low internal resistance makes them well-suited for applications that require high peak currents.
