When soldering supercapacitors to a PCB, the temperature & time

that the body of the supercapacitor sees during soldering can have a

negative effect on performance. We advise following these guidelines:

• Do not immerse the supercapacitors in solder. Only the leads

should come in contact with the solder.

• Ensure that the body of the supercapacitor is never in contact with

the molten solder, the PCB or other components during soldering.

• Excessive temperatures or excessive temperature cycling during

soldering may cause the safety vent to burst or the case to shrink or

crack, potentially damaging the PCB or other components, and

significantly reduce the life of the capacitor.

HAND SOLDERING

Keep distance between the supercapacitor body and the tip of the

soldering iron and the tip should never touch the body of the capacitor.

Contact between supercapacitor body and soldering iron will cause

extensive damage to the supercapacitor, and change its electrical

properties. It is recommended that the soldering iron temperature

should be less than 350°C, and contact time should be limited to less

than 4 seconds. Too much exposure to terminal heat during soldering

can cause heat to transfer to the body of the supercapacitor,

potentially damaging the electrical properties of the supercapacitor.

WAVE SOLDERING

Only use wave soldering on Radial type supercapacitors. The PCB

should be preheated only from the bottom and for less than 60

seconds, with temperature at, or below, 100°C on the top side of

the board for PCBs equal to or greater than 0.8 mm thick.

REFLOW SOLDERING

Infrared or conveyor over reflow techniques can be used on these

supercapacitors. Do not use a traditional reflow oven without clear

rated reflow temperature for supercapacitors.

TEST METHODS

SCC LE Series SuperCapacitors

New Low ESR Cylindrical Supercapacitors

IEC Capacitance Test Method

• Capacitance is measured using a Keithley 2400 or 2602 Meter

• Procedure

• Charge Capacitor to Rated Voltage at room temperature

• Disconnect parts from voltage to remove charging effects

• Discharge cells with a constant current I determined by

4 * C * VR

• Noting V1, t1, V2, t2 and performing the calculation for C

DC ESR Measurement

• Six steps capacity and ESRDC Test Method is used as illustrated

in the figure right.

• Tests are carried out by charging and discharging the capacitor

for two cycles at rated voltage and half rated voltage

• C = (CDC1+CDC2) / 2

• ESRDC = (ESRDC1 + ESRDC2) / 2

Where: CDC1 = I2*(t5-t4)/(V3-V4)

CDC2 = I2*(t11-t10)/V9-V10)

ESRDC1 = (V5-V4)/I2

ESRDC2 = (V11-V10)/I2

I1= I2= 75mA/F

Maximum Operating Current

• This is the maximum current when capacitor temperature rise of

the capacitor during its operation is less than 15°C

Maximum Peak Current

• This is the maximum current in less than 1 sec

Watt Density

• Watt Density = (0.12*V² / RDC) / mass

Energy Density

• Energy density = (½ CV²) / (3600*mass)

POLARITY / REVERSE VOLTAGE

SCC LE Series SuperCapacitors

New Low ESR Cylindrical Supercapacitors

In principal the positive and negative electrodes of the super-

capacitors are symmetrical and in theory they should not have a

polarity but for product consistency and for optimum performance

the negative polarity is marked because the capacitors do not

discharge completely when in use. It is recommended that the

polarity should be used as marked. If the polarity is reversed the

circuit will not have a catastrophic failure but the circuit will see a

much higher leakage current for a short duration of time and the life

time of the super-capacitors will be reduced.

LIFE TIME AND TEMPERATURE PERFORMANCE

The life of a supercapacitor is impacted by a combination of

operating voltage and the operating temperature

according to the following equation:

time to failure, t ∞ Vn * exp (-Q / k*T) …………..(1)

where V is the voltage of operation, Q is the activation energy in

electron volts (eV), k is the Boltzmann’s constant in eV and T is the

operating temperature in °K (where K is in degrees Kelvin). Typical

values for the voltage exponent, n, is between 2.5 - 3.5, and Q is

between 1.0 - 1.2 eV in the normal operating temperature range of

40° to 65°C.

The industry standard for super-capacitor end of life is when the

equivalent series resistance, ESR, increases to 200% of the original

value and the capacitance drops by 30%. Typically a super-

capacitance shows an initial change in the ESR value and then

levels off. If the capacitors are exposed to excessive temperatures

the ESR will show a continuous degradation. In the extreme case, if

the temperatures or voltages are substantially higher, than the rated

voltage, this will lead to cell leakage or gas leakage and the product

will show a faster change in the ESR which may increase to many

times the original value.
