The new series of cylindrical electrochemical double-layer capacitors 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, and Pulse Power Applications.

Precautionary Warning!
If these 3-Prong Solder Pin parts are used in series-connected module assembly, these parts utilize the outer aluminum casing as the positive connection. Do
not use parts if the shrink wrap is split open or if the casing is exposed. Maintain proper part spacing in module designs, as part-to-part potential can create a
deadly situation (i.e. try to avoid having part one very close to part 20 or higher, and so on). It is recommended to have the tops of parts covered with insulation
material to avoid inadvertent shorting in module designs. If you have any questions please contact AVX.
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 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 components, and
signicantly reduce the life of the capacitor.
PRECAUTION: For all products with shrink wrap sleeves, washing in any type of cleaning
agent is prohibited. During all soldering processes, it’s recommended to protect the
shrink wrap from any kind of liquid (including but not limited to: water, strong acid,
strong alkali, strong oxidizing solutions, and strong solvents) to avoid the risk of
damage, cracking, and fading of the outer shrink wrap.
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 capacitor. 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.
Solder Temperature (ºC) Suggested Solder Time (s) Maximum Solder Time (s)

240 79
250 57

WELDING RECOMMENDATIONS
When weld-assembling modules, it is recommended using 2mm thick
1060 aluminum.
For WELDABLE PIN TYPE 2-PIN cells, it is recommended to use 0.6 optical
ber 600W laser welding machine. These cells need 30 weld points.
For WELDABLE PIN TYPE AXIAL cells, the same parameters are
recommended, however these cells need 60 weld points.
Be sure to refer to page 4 for exact pin type and mechanical dimensions of
respective weldable pin cells.

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 effects
• Discharge cells with a constant current I determined by 4 * C * VR
• Noting V1, t1, V2, t2 and performing the calculation for C
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
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

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-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.

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.
