[Brand] American PowerStor [Model] 2.7V6.0F [Volume] 8*30 (mm) diameter * height Introduction to Farah Capacitor: The Farad capacitor is an electric double layer capacitor. It is the largest one of the world's largest electric double layer capacitors. The basic principle is the same as other types of electric double layer capacitors. The double layer structure achieves an extra large capacity. Features of super capacitors: (1) The charging speed is fast, and it can reach more than 95% of its rated capacity by charging for 10 seconds to 10 minutes; (2) The cycle life is long, the frequency of deep charge and discharge cycles can reach 10,000 to 500,000 times, there is no "memory effect", and there is no problem of over-discharge; (3) The high current discharge capacity is super strong, the energy conversion efficiency is high, the process loss is small, and the high current energy cycle efficiency is ≥90%; (4) High power density, up to 300W/KG~5000W/KG, equivalent to 5~10 times of battery; (5) The raw material composition, production, use, storage and dismantling process of the product are not polluted, and it is an ideal green power source; (6) The charging circuit is simple, no charging circuit like rechargeable battery is needed, and long-term use is maintenance-free; (7) Good ultra-low temperature characteristics, temperature range -40 ° C ~ +70 ° C; (8) Easy to detect, the remaining power can be read directly; (9) The capacity range is usually 0.01F--1000F, and the withstand voltage is often low (a few volts to more than ten volts, and the newly developed is also more than twenty volts). Supercapacitors can be made into super capacitor modules for high capacity requirements. Disadvantages: (1) At present, the withstand voltage of super capacitors is not high. The overvoltage protection circuit is indispensable in actual use. It is often the case that two or more supercapacitors are connected in series to access a large voltage environment. This is not the right approach. Because the capacitance of the capacitor is different, the quality of the capacitor is not the same. After repeated charging and discharging in the later stage, it is easy to cause the local unit to overcharge and break down. (2) The supercapacitor is not a battery after all, and there is a problem that the voltage gradually drops with discharge, so a complicated output circuit is required. application ◆ The low impedance of farad capacitors is essential for many high power applications today. For fast charge and discharge, a small ESR of a farad capacitor means a greater power output. [1] ◆ Instantaneous power pulse application, short-term power support for important storage and memory systems. Application examples 1, fast charging application, charging for a few seconds, discharge for a few minutes. Such as electric tools, electric toys; 2. In a UPS system, a supercapacitor provides instantaneous power output as a supplement to the backup power so
