【Voltage】: 3.5V 【Capacity】: 0.1F 【Use temperature】: -40-85℃ 【Volume】: 7.5*2.5mm 【Brand】: NEC/TOKIN 【Manufacturing factory】: Japan [Polarity]: The long foot is the positive pole (when charging, the positive pole of the charging is opposite to the positive pole of the capacitor) 【Features】: 1. Fast charging speed. Electrochemical capacitor charging is a physical process of charging and discharging the electric double layer, which can be completed in tens of seconds to minutes, which is a real fast charging. 2. Long service life, can actually reach more than 100,000 times, which is 10-100 times higher than that of batteries. 3. Wide operating temperature range and superior low temperature performance. 4. The charging and discharging circuit is simple, and there is no need for complex charging circuits like rechargeable batteries. 5. Less pollution to the environment, especially carbon-based electrochemical capacitors. 【use】: 1. As a backup power supply in electronic products with memory storage function 2. Used as a power supply for low-power devices 3. It is used in electric starting systems of various internal combustion engines with batteries
