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 components, 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

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

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.

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.

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

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 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-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.
