## **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.
- 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.
**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 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 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**
Procedure: Charge module under constant current to rated voltage at room temperature, then hold 10 minutes on charge under constant voltage. After 10 minutes, discharge under constant current (as shown in chart below), recording voltage at V1, V2, and time intervals at t1 and t2. Use the capacitance formula to determine cap value.

**==> picture [88 x 30] intentionally omitted <==**
## **DC ESR Measurement**
A six-step ESRDC test method is illustrated to the right and carried out as follows:
1. Rest 10 seconds
2. Charge under constant current (I1) to rated voltage (VR)
3. Rest 5 seconds
4. Rest 10 seconds, record V3 and t4
5. Discharge under constant current (I2) to half rated voltage, record I2, V4, and t5

**----- End of picture text -----**
6. Rest 5 seconds, record V5 and t6
Repeat steps 1-6 recording I, V, and t accordingly, finally discharging to below 0.1V under constant current (I2).
Formulas to calculate:
- Two cycle discharge capacitances: 𝐶𝐶𝑑 𝑑1 = 𝐼𝐼2 × ~~(~~ ( 𝑉𝑉𝑡𝑡53−𝑡𝑡−𝑉𝑉44 ))[; ][𝐶𝐶][𝑑][𝑑2][= 𝐼𝐼][2][ ×] (( 𝑡𝑡𝑉𝑉119−𝑉𝑉−𝑡𝑡1010 )
- • = ( 𝐶𝐶𝑑 𝑑1+𝐶𝐶𝑑 𝑑𝑑 ~~)~~ Discharge capacitance: 𝐶𝐶𝑑 𝑑 2
- • Two cycle discharge DC ESR: 𝐸 𝐸𝐸𝑑 𝑑1 = ~~(~~ 𝑉𝑉5𝐼𝐼−𝑉𝑉𝑑 4 ) ; 𝐸 𝐸𝐸𝑑 𝑑2 = ( 𝑉𝑉11𝐼𝐼−𝑉𝑉𝑑 10 ) • Discharge DC ESR: 𝐸 𝐸𝐸𝑑 𝑑 = ( 𝐸 𝐸𝐸𝑑 𝑑1+𝐸 𝐸𝐸𝑑 𝑑𝑑 )
- 2
Note: I1 = I2 = 75mA/F, the rated capacitance in the chart means discharge capacitance, and DC ESR (ESRDC) means discharge DC resistance.

## **SCC Series**
## **High Capacitance Cylindrical SuperCapacitors**
## **TEST METHODS**
## **Maximum Continuous Current**
- This is the maximum current when temperature rise of the supercapacitor during its operation is less than 15°C
## **Maximum Peak Current**
- This is the maximum current during 1 second time interval (dt)
## **Watt Density**
- Watt Density = (0.12*V² / RDC ) / mass
## **Energy Density**
- Energy Density = (½ CV²) / (3600*mass)
## **POLARITY AND 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.
## **LIFETIME AND TEMPERATURE PERFORMANCE**
The life of a supercapacitor is impacted by a combination of operating voltage and the operating temperature according to the following Time to Failure equation:
**==> picture [77 x 20] intentionally omitted <==**
where V is the operating voltage, Q is the activation energy in electron volts (eV), k is the Boltzmann constant in eV, and T is the operating temperature in Kelvin (K). 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 specified value and the capacitance drops by 30% from specified value. Typically a supercapacitor shows an initial “jump” in the ESR value and then levels off. If the supercapacitors are exposed to excessive temperatures the ESR will show a continuous degradation (increase). In the extreme case, if the temperature or voltage are substantially higher than the rated specifications, this could result in the part venting and the product showing a faster degradation of capacitance and ESR, which may be many times the specified value.

## **Storage**
Capacitors may be stored within the temperature range of -40°C to +70°C with humidity < 60%. Lower storage temperature is preferred as it extends the shelf life of the capacitor.

Optimum storage conditions are as follows:
- 25°C and RH ≤60% without voltage applied
- Not in direct sunlight
- Not in direct contact with water, salt oil or other chemicals
- Not in direct contact with corrosive materials, acids, alkalis, or toxic gases
- Not in dusty environments
- Not in environments with shock and vibration conditions
