Electric Double Layer Capacitors (EDLC) and Supercapacitors

An Electric Double Layer Capacitor (EDLC) is a form of capacitor which has two layers of electrodes separated by an electrolyte, usually in the form of a porous solid. EDLCs are used mainly for short-term energy storage, due to their low cost, high capacitance, low leakage and fast charging and discharging characteristics. In contrast, supercapacitors are larger, heavier and more expensive, but have the ability to store energy over multiple charge/discharge cycles for extended periods of time. The DGH155Q5R5 is an Electric Double Layer Capacitor (EDLC) which is designed for use in extended operating temperatures up to 155ºC and ultra high temperatures up to 175ºC. It is a high reliability and high capacitance EDLC that offers outstanding performance under extreme conditions.The application field of the DGH155Q5R5 EDLC is mainly in industrial applications where high capacitance is needed in harsh environments. This could include battery back-up systems, uninterruptable power supplies, power line filtering, solar energy storage, high temperature automotive applications, and more. The DGH155Q5R5 is designed to provide a reliable energy storage solution in these types of environments.The working principle of an EDLC is based on the electrostatic attraction between two layers of electrodes in an electrolyte. The positive ions in the electrolyte are attracted to the negative electrode, while the negative ions are attracted to the positive electrode. The resulting double layer of charges acts like a capacitor and results in a higher capacitance than a typical capacitor.The DGH155Q5R5 has a capacitance range of up to 15 Farads and a max voltage rating of 5.5 V. Its construction and design consists of a capacitor body, an embedded aluminum oxide dielectric material, two electrodes, and an electrolyte. The EDLC is sealed in a high temperature and highly antioxidant-resistant epoxy resin. The EDLC utilizes the principle of electrostatic attraction between two layers of charged ions to store energy.The main benefit of an EDLC such as the DGH155Q5R5 is its ability to charge and discharge quickly. EDLCs are generally able to charge and discharge up to 10,000 times faster than a traditional capacitor. This makes them suitable for applications where very fast charge and discharge times are needed. Additionally, EDLCs are able to recover energy even at high temperatures. This is beneficial for applications operating in high temperature environments, such as automotive applications and those involving solar energy.In summary, the DGH155Q5R5 is an Electric Double Layer Capacitor (EDLC). It is designed to provide high capacitance and reliable energy storage in harsh environments. Its application field is mainly in industrial applications where high capacitance is needed in high temperatures. The working principle of the DGH155Q5R5 is based on the electrostatic attraction between two layers of electrodes in an electrolyte. The main benefit of an EDLC such as the DGH155Q5R5 is its ability to charge and discharge quickly and to recover energy even at high temperatures.
