SOLDERING RECOMMENDATIONS
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 soldering 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 temperature 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.

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

DCL Measurement @ 25°C
• DCL is measured using a DMM recording voltage across a resistor
• Charge Capacitor to Rated Voltage at room temperature for 72 Hours
• Disconnect parts from voltage to remove charging effects
• Noting V1 , t1 , V2 , t2 after 5 minutes and 25 minutes and performing the calculation for
I = C * (V1 – V2)/(t2 – t1)
Initial ESR Measurement @ 25°C
• Using an Agilent 4263B LCR Meter and a Kelvin connection
• Measure at frequency of 1000 Hz
• Measurement Voltage of 10mV
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

TEST METHODS (continued)
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
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.
