Specification:
Rated Voltage: 16.8V
Rated Capacity: 500F
Type: Single Row 16.8V 500F Super Farad Capacitor

Feature:
Fast charging speed, charging for more than 95% of its rated capacity from 10 seconds to 10 minutes
Long cycle life, deep charge and discharge cycle usage up to 10,000 to 500,000 times, no "memory effect", no over-discharge problem
High current discharge capacity, high energy conversion efficiency, low process loss, high current energy cycle efficiency ≥90%
The power density is relatively low, about 2W/KG~3W/KG, which is equivalent to 1/5~1/10 of lead-acid batteries.
The raw material composition, production, use, storage and dismantling process are not polluted, and it is an ideal green power source.
The charging circuit is simple, no charging circuit like rechargeable battery, long-term use maintenance-free
Excellent ultra-low temperature characteristics, wide temperature range -40°C -70°C
Easy to detect, the remaining power can be read directly
The capacity range is usually 0.01F--3400F, 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).
Super capacitors can be made into super capacitor modules for high capacity requirements.

Disadvantages:
The super capacitor has a low withstand voltage. The overvoltage protection circuit is indispensable in actual use. It is not right to connect too many (more than 10) single-farad capacitors in a single module. Because of the leakage of the capacitor, it is easy to cause the local unit to overcharge and break down after multiple charging and discharging in the later stage. Therefore, high-voltage circuits. Try to choose a capacitor with a high withstand voltage value. Try to reduce the number of capacitors in series.
After all, the super capacitor is not a battery, 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.
Instantaneous power pulse application, short-term power support for critical storage and memory systems.

Application examples
1) Fast charging application, charging in a few seconds, discharging in a few minutes. Such as electric tools, electric toys
2) In UPS systems, supercapacitors provide instantaneous power output as a supplement to the backup power supply for engines or other uninterrupted systems.
3) Applied to energy-rich, power-poor energy sources such as solar energy
4) Power support when the bus is switched from one power source to another
5) Small current, long-term continuous discharge, such as computer memory backup power
