SOLDERING RECOMMENDATIONS
When soldering supercapacitors to a PCB, the temperature &
time that the body of the supercapacitor sees during soldering
can have a negative eect 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 com-
ponents, and signicantly 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 ca-
pacitor. 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 reow techniques can be used on
these supercapacitors. Do not use a traditional reow oven with-
out clear rated reow temperature for supercapacitors.

TEST METHODS
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 eects
• Discharge cells with a constant current I determined by
4 * C * VR
• Noting V1, t1, V2, t2 and performing the calculation for C
Voltage
t1 t2 Times (s)
I – Discharge Current [mA], 4 * C * VR VR – Rated Voltage
V1 – Initial Test Voltage, 80% of VR
V2 – Final Test Voltage, 40% of VR
t1 – Initial Test time
t2 – Final Test time
C = I * (t2 – t1) / (V1 – V2)
DCL Measurement @ 25°C
• DCL is measured using a Multimeter with high internal impedance
across a resistor
• Charge Capacitor to Rated Voltage at room temperature for
72 Hours
• Disconnect parts from Voltage by opening switch 1 (Stabilize
for 10 Min)
• Measure Voltage across a known Valued Resistor (1K Ohm)
• Calculate DCL = V/R
012418
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 gure 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
In principal the positive and negative electrodes of the
supercapacitors 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 o. 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.
