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 significantly 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 Radial Lead Type Weldable Pin Type 2-pin 400F, 600F parts Radial Bent Lead Type 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. 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.

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 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.
