Supercapacitors are a new type of electrochemical component that store energy by polarizing electrolytes. There is no chemical reaction during the energy storage process, and this energy storage process is reversible, so the supercapacitor can be repeatedly charged and discharged hundreds of thousands of times.
An ordinary electrolytic capacitor is a static charge storage medium, and the charge can be retained for a long time, which has a wide range of uses and is an indispensable electronic component in the field of electronic power.
Both supercapacitors and ordinary capacitors are capacitors. What are the advantages of supercapacitors compared with ordinary supercapacitors?
1. Compared with ordinary capacitor, the capacitance of the super capacitor is large, which has reached the Farad level. The capacitance of ordinary capacitors is as small as microfarads.
2. The super capacitor can be repeatedly charged and discharged hundreds of thousands of times, and the use time is long. Ordinary capacitors can only be charged and discharged hundreds of times, and the use time is short.
3. The charging speed is faster than that of ordinary capacitors, and it can reach more than 95% of the rated capacitance in 10 seconds to 10 minutes.
4. Super capacitors have good ultra-low temperature characteristics and can work at -40°C to +70°C, while the performance of ordinary capacitors is greatly reduced at low temperatures.
5. The charge retention ability is strong, and the leakage is small. The ordinary capacitor needs to be charged frequently to maintain the state.
6. The production and production process of super capacitor materials does not cause environmental pollution, and is an ideal green power source, while ordinary capacitors cause pollution and impact on the environment.
Due to these advantages of supercapacitors, they are often used in industries such as power supplies for electronic equipmen, new energy vehicles, emergency lighting systems and high-power electrical pulse equipment. Common capacitors are mainly used in power supply filtering, signal filtering, signal coupling, resonance, filtering, compensation, charging and discharging, energy storage, various tributaries and other circuits.
Some unscrupulous manufacturers may mix supercapacitors with good quality and low quality to sell. Therefore, you must choose carefully when purchasing supercapacitors.
Select a reliable manufacturer when purchasing ceramic capacitors can avoid a lot of unnecessary trouble. JEC original manufacturer not only has full models of ceramic capacitors with guaranteed quality, but also offers worry-free after-sales. JEC factories has passed ISO9001:2015 quality management system certification; JEC safety capacitors (X capacitors and Y capacitors) and varistors have passed the certification of various countries; JEC ceramic capacitors, film capacitors and super capacitors are in line with low carbon indicators.
