Quick charge app, charge in seconds, discharge in minutes. Such as power tools, electric toys; in UPS systems, supercapacitors provide instantaneous power output as a supplement to the backup power supply of engines or other uninterrupted systems; used in energy-sufficient, power-poor energy sources, such as solar energy; when the bus from a Power support when one power source is switched to another power source; small current, continuous discharge for a long time, such as computer memory backup power supply.

Application areas:

Usage:

Supercapacitors cannot be used in the following states:

1) Temperatures above the nominal temperature

When the capacitor temperature exceeds the nominal temperature, the electrolyte will be decomposed, and the capacitor will heat up and the capacity will decrease.

In addition, the internal resistance increases and the service life is shortened.

2) more than Rated voltage voltage

When the capacitor voltage exceeds the nominal voltage, the electrolyte will be decomposed, and the capacitor will heat up and the capacity will decrease.

In addition, the internal resistance increases and the service life is shortened. Therefore, reducing the operating voltage can improve the service life.

3) Loading of reverse voltage or AC voltage

1. The effect of ambient temperature on supercapacitors

The service life of supercapacitors is affected by the operating temperature. Generally, if the operating temperature is increased by 10°C, the service life of the supercapacitor will be shortened by half. Please try to use it in a low temperature environment lower than the operating temperature. If it is used beyond the operating temperature, it may cause rapid deterioration of characteristics and damage.

The use temperature of supercapacitors should not only confirm the surrounding temperature and internal temperature of the device, but also the radiation heat from the heating element (power transistor, resistor, etc.) in the device, and the self-heating temperature caused by the ripple current. Also, do not install the heating element near the supercapacitor.

2. Please use the capacitor according to the positive and negative signs of the capacitor.

3. Please avoid using super capacitors in the following environments.

a) An environment that is directly splashed with water, salt water and oil, or an environment that is in a condensation state and is full of gaseous oil or salt.

b) An environment full of harmful gases (hydrogen sulfide, sulfurous acid, chlorine, ammonia, bromine, methyl bromide, etc.).

c) Environment splashed with acidic and alkaline solvents.

d) Direct sunlight or dusty environment.

e) environments subject to excessive vibration and shock.

4. Avoid overheating the capacitor during the soldering process (1.6mm printed circuit board should be 260°C during soldering, and the time should not exceed 5s).

5. Please avoid circuit wiring between the supercapacitor leads or between the solder joints of the connection board.

6. When using over-voltage or exceeding the operating temperature range beyond the rated conditions, it may cause the pressure valve to act, and the electrolyte will be ejected. Therefore, use a design approach that takes into account the possibility of this anomaly.

7. When charging and discharging rapidly, a voltage drop (also called IR drop) caused by internal impedance occurs at the beginning of charging and at the beginning of discharge. Therefore, please adopt a design method that takes into account the range of voltage variation.

8. Power-type large-capacity products (products above 10F) if the terminals are short-circuited in the charging state, there will be hundreds of amps of current flowing, which is dangerous. Please do not install or remove it while charging.

9. Do not put the capacitor into the dissolved solder, only stick the solder on the lead pins of the capacitor. Do not allow the welding rod to touch the capacitor heat shrink tube.

10. After installation, do not forcibly twist or tilt the capacitor.

11. When the supercapacitors are used in series, there is a problem of voltage balance between the cells.
