Super Farad Capacitors 14 Value 0.22F to 4F Capacitance 14 Pcs Assortment Box

1. Super capacitor (supercapacitor), also known as electric double layer capacitor (Electrical Doule-Layer Capacitor), gold capacitor, farad capacitor, through the electrolyte to the polarization energy storage. It is an electrochemical device, but is not a chemical reaction in which energy storage process, this energy storage process is reversible, which is why the super capacitors can be repeated charge and discharge hundreds of thousands of times.

2. It is between the energy storage device capacitors and batteries, both as a capacitor can quickly charge and discharge characteristics, but also has a storage mechanism of electrochemical cells. Supercapacitors may be divided into two categories: (1) activated carbon as an electrode material for electric double layer capacitor electrode mechanism accumulated charge, commonly referred to as an electric double layer capacitor (DLC); (2) to a conductor or ruthenium dioxide polymeric materials such as an anode, the charge storage mechanism to the redox reaction, commonly referred to as an electrochemical capacitor.

3. As a new energy storage element, the capacitance of the electrochemical capacitor can be high level or even thousands of Da Fala Fala, enables rapid charge and discharge currents and large power generation, while using (in extremely low temperature and other extreme environments -40 ~ + 80 ℃ work), no environmental pollution, and can be welded, there is no battery soldering weak and short-circuit problem, low internal impedance, cell voltage: 5.5V energy density is several times more than lithium-ion batteries


These features make electrochemical capacitors are widely used in digital and electronic products, electric motor can be used as toys, voice IC, LED light emitters and other small power electrical drive power. Can replace the rechargeable batteries in the solar warning lights, beacon lights and other solar products.
