SCM Series
Series-Connected Super Capacitor Modules
This new series of electrochemical, double-layer, series-connected SuperCapacitor modules
offers 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. Offers great solutions to hold up, energy harvesting, pulse power
applications, and battery replacement.

QUALITY INSPECTION
TERMINATION
Parts are tested for life cycle, high temperature load life, temperature
characteristics, vibration resistance, and humidity characteristics.
See pages 2-5 for more information.
These SuperCapacitors are compatible with hand soldering, as well
as reflow and wave soldering processes, so long as appropriate
precautions are followed. See page 11 for more information.
LEAD-FREE COMPATIBLE
COMPONENT
For RoHS compliant products, please
select correct termination style.

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

POLARITY / REVERSE VOLTAGE
For product consistency and optimum performance, it is recommended that the capacitor be connected with polarity indicated. Reversing polarity
could result in permanent damage to the circuit including 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 SuperCapacitor
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.

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.
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.
Solder Temperature
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.

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.
Warnings
Regulatory
• 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
• UL 810A
• RoHS Compliant
• Reach Compliant / Halogen Free
Emergency Applications
• If housing is leaking:
• Skin contact: use soap and water thoroughly to wash the
area of the skin
• Eye contact: flush with flowing water or saline, and
immediately seek medical treatment
• Ingestion: immediately wash with water and seek medical
treatment
Transportation
Maximum Solder
(ºC)
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
>40°C / 70% 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
