QUALITY INSPECTION
Parts are tested for life cycle, high temperature load life, temperature
characteristics, vibration resistance, and humidity characteristics.
See pages 2-5 for more information.
This new series of electrochemical, double-layer, series-connected supercapacitor modules
o󰀨ers excellent pulse power handling characteristics based on the combination
of very high capacitance and very low ESR. Used by themselves or in conjunction with
primary or secondary batteries, they provide extended back up time, longer battery life, and
provide instantaneous power pulses as needed. O󰀨ers great solutions to hold up, energy
harvesting, pulse power applications, and battery replacement.

Voltage
t1 t2 Times (s)
I – Discharge Current [mA], 4 * C * VR VR – Rated Voltage

DC ESR Measurement
• Six steps capacity and ESRDC Test Method is used as illus-
trated 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 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 supercapacitors 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 supercapacitor 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-
capacitor 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.

SAFETY RECOMMENDATIONS
Warnings
• To avoid short circuit, after usage or test, supercapacitor voltage
needs to discharge to ≤ 0.1V
• Do not apply over-voltage, reverse charge, burn or heat higher
than 150°C, explosion-proof valve may break open
• Do not press, damage or disassemble the supercapacitor,
housing could heat to high temperature causing burns
• If you observe overheating or burning smell from the capacitor
disconnect power immediately, and do not touch
Emergency Applications
• If housing is leaking:
• Skin contact: use soap and water thoroughly to wash the
area of the skin
• Eye contact: ush with owing water or saline, and
immediately seek medical treatment
• Ingestion: immediately wash with water and seek medical
treatment

Regulatory
• UL 810A
• RoHS Compliant
• Reach Compliant / Halogen Free
Storage
• Capacitors may be stored within the operating temperature
range of the capacitor
• Lower storage temperature is preferred as it extends the shelf
life of the capacitor
• Do not store the supercapacitors in the following environments
• High temperature / high humidity environments
>70°C / 40% RH
• Direct sunlight
• In direct contact with water, salt oil or other chemicals
• In direct contact with corrosive materials, acids, alkalis, or
toxic gases
• Dusty environment
• In environment with shock and vibration conditions
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 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 reow techniques can be used on these
supercapacitors. Do not use a traditional reow oven without clear
rated reow temperature for supercapacitors.
