5. Do not use in a circuit where quick charge and

discharge are repeated very often.

Application Guidelines

In a circuit where quick charge and discharge are

repeated very often, the capacitor will become

overheated, which may cause a decrease in the

capacitance, an increase in the internal resistance, and

cause electrolyte leakage or damage to the capacitor in

some cases. Reduce the charge and discharge currents

while selecting a capacitor with low internal resistance,

and make sure that the capacitor surface temperature

does not rise more than 10˚C.

1. Do not apply a reversed voltage.

Reverse polarity is not recommended. If a reversed

voltage is applied for a long time, the leakage current will

increase abruptly, which may cause a decrease in the

capacity, an increase in the internal resistance, and cause

electrolyte leakage or damage to the capacitor in some

cases.

2. Do not apply any voltage higher than the operating

maximum voltage.

6. Super capacitor life depends on the ambient

temperature.

Supercapacitors are rated with a nominal recommended

working or applied voltage. If an over voltage is applied to

the capacitor, the leakage current will increase abruptly

and the capacitor will become overheated, which may

cause a decrease in the capacity, an increase in the

internal resistance, and cause leakage or damage to the

capacitor in some cases. But, surge voltage can usually

be tolerated by the super capacitor.

The lifetime of super capacitor is seriously affected by

change in ambient temperature. If the temperature is

lowered by 10˚C, the lifetime will be approximately

doubled. As a result, it is recommended to use the super

capacitor at the lowest temperature possible to decrease

internal degradation and ESR increase. If the capacitor is

used at a temperature exceeding its maximum guaranteed

temperature, not only is its life shortened, but increased

vapor pressure of electrolyte or electrochemical reactions

may increase the internal pressure, and cause electrolyte

leakage or damage to the capacitor in some cases.

3. Ripple Current

Supercapacitors have a higher internal resistance than

aluminum electrolytic capacitors and are more

susceptible to internal heat generation when exposed to

ripple current, this may cause a decrease in the capacity,

an increase in the internal resistance, and cause electrolyte

leakage or damage to the capacitor in some cases.

7. Voltage drop occurs during back-up operation.

In applications where the discharge current is large, or a

large current flows instantaneously, super capacitor may

not operate at the start of discharge because of the large

voltage drop (IR drop) caused by the capacitors internal

resistance (ESR). The formula for the voltage drop, Vdrop,

during a discharge at I current for t seconds is:

4. Charging and Discharging.

Supercapacitors can be charged using various methods,

including constant current, constant power, constant

voltage or by paralleling to an energy source, i.e. battery,

fuel cell, DC converter, etc. In general, characteristics of

constant current and constant resistance discharging are

respectively represented by the equation (1) and (2) below:

Vdrop = I(R + t/C)

8. Series Connecting of super capacitor.

Discharging time (t) of constant current discharge

t = C x (Vo-V1) / l…..(1)

Discharging time (t) of constant resistance discharge

t = -CRIn(V1/Vo)…..(2)

A series connection can cause an imbalance in the

voltage across a super capacitor causing the capacitors

to have an over voltage which can cause electrolyte

degradation, excessive gas generation, increased ESR,

decrease in capacitance and reduced life. To prevent

voltage imbalance, passive or active voltage balancing is

recommended. Passive voltage balancing should be

performed using divider resistors placed in parallel with

the super capacitors. Using resistance values between100

Ω/F to 470 Ω/F are recommended.

t = discharging time(s)

vo = initial voltage (v)

v1 = terminal voltage (v)

l = current during back-up (A)

The maximum recommended charge current, I, for a super

capacitor is calculated as follows:

I = Vw / 5R

where Vw is the charge voltage and R is the super

capacitors DC ESR

9. About vibration.

14. Circuit board cleaning after soldering.

A terminal blank, a terminal bend, and a crease may occur

by adding too much vibration to a capacitor. When there

becomes too much vibration, please contact our company.

Circuit boards can be immersed or ultrasonically cleaned

using suitable cleaning solvents for up to 5 minutes and

up to 60˚C maximum temperatures. The boards should be

thoroughly rinsed and dried.

10. When used on a double sided printed circuit board,

do not design exposed circuit board traces under the

super capacitor.

An electrical short could occur if the super capacitor

electrolyte should leak onto the circuit board.

11. Do not store in high temperature and high humidity

conditions.

Avoid high temperature or high humidity or direct rays

when storing capacitors. Avoid direct contact with water,

salt water or oil, toxic gases, or dusty environment.

15. Be careful not to apply an excessive force to the

capacitor body, terminals or lead wires.

If the capacitor body is subjected to stress such as

grabbing, falling, bend, pushing or twisting after mounted,

its terminals may come off, leading to open, short or liquid

leakage.

12. When soldering the super capacitor to the wiring

board, do not attach the body of the super capacitor to

the circuit boards.

If the body of the capacitor is attached directly to the

circuit board, the flux or solder can blow through the

mounting holes in the circuit board, possibly causing

internal damage to the super capacitor.

16. Emergency procedures.

If a super capacitor is found to be overheating or starts to

smell, immediately switch off the unit’s main power or load

to stop operation. Do not expose your face and hands if

exposed to electrolyte. Wash exposed area thoroughly

with soap and water.

13. Do not overheat when soldered.

Excessive heat may cause deterioration of the electrical

characteristics of the aerogel super capacitor, electrolyte

leakage or an increase in internal pressure.
