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 not in contact with
the PCB or other components during soldering. Temperature
cycling during soldering may cause the case to shrink or crack,
potentially damaging the PCB or other components.
HAND SOLDERING
Keep some distance between the supercapacitor body and the tip
of the soldering iron; contact between supercapacitor body and sol-
dering iron will cause extensive damage to the supercapacitor. It is
recommended that the soldering iron temperature should be less
than 350°C, and contact time should be limited to no more 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 supercapacitor.
WAVE SOLDERING
Only use wave soldering on Radial type supercapacitors. The PCB
should be preheated for no longer than 60 seconds, with tempera-
ture at, or below, 100°C. Soldering tin should be 0.8mm or thicker.
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
SCM Series Supercapacitor Modules
High Capacitance 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
SCM Series Supercapacitor Modules
High Capacitance 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.
