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. 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 350C, 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. 4 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, 100C. Soldering tin should be 0.8mm or thicker. Solder Temperature (C) 220 240 250 260 Suggested Solder Time (s) 7 7 5 3 Maximum Solder Time (s) 9 9 7 5 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. 100317 SCM Series Supercapacitor Modules High Capacitance Cylindrical Supercapacitors TEST METHODS IEC Capacitance Test Method Initial ESR Measurement @ 25C * 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 * Using an Agilent 4263B LCR Meter and a Kelvin connection * Measure at frequency of 1000 Hz * Measurement Voltage of 10mV Voltage (V) VR 30 min V3 ESR Drop V1 V2 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 I1 = I2 = 75mA/F I1 VR V1 Cycle 1 V2 V7 I1 V3 Cycle 2 V8 Step 4 t1 t2 Step 4 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) V9 Step 2 Step 2 Step 3 Step 6 Step 6 Step 3 V5 Step 1 Step 1 V6 V11 V4 V10 Step 5 DCL Measurement @ 25C * 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 Step 5 I2 0 t1 t2 t3 t4 I2 t5 t6 t7 t8 t9 t10 t11 t12 Maximum Operating Current * This is the maximum current when capacitor temperature rise of the capacitor during its operation is less than 15C Maximum Peak Current * This is the maximum current in less than 1 sec Multimeter * Watt Density = (0.12*V / RDC) / mass - + Energy Density + 1k DC Power Supply Watt Density * Energy density = (1/2 CV) / (3600*mass) 1 - 100317 5 SCM Series Supercapacitor Modules High Capacitance Cylindrical Supercapacitors 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 super-capacitors 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 65C. The industry standard for super-capacitor 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 supercapacitance 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.
