5.5V 2F-L farad capacitor
Handling Precautions and Guidelines
For safety application, please contact Shandong Godencell directly for any technical specifications, handling precautions and guidelines critical to application.
1. Voltage drop
Pay particular attention to the instantaneous working current and voltage drop due to the supercapacitor’s interal resistance when used in backup mode. The discharging current level is different depending on the supercapacitor’s inernal resistance.
2. Series connection
When connecting supercapacitors in series, add a bleeder resistor in parallel with each supercapacitor by taking the leak current into consideration so that the balanced of voltages is not disrupted.
3. Solder of supercapacitor
When soldering a supercapacitor to a printed circuit board, excessive heat stress could cause the deterioration of the supercapacitor’s electrical characteristics. For example, the intergrity of the seal can be compromised causing the electrolyte to leak,and short circuits could occur in addition to failure of appearance.
Please observe the following guidenlines:
(1) Manual soldering
Do not touch the supercapacitor body with a soldering iron. Solder the capacitor using a soldering tip temperature of 350 oC or less for 4 seconds or less. Solder the capacitor three times or less at intervals of 15 seconds or more.
(2) Folw soldering
a) Do not dip the body of the supercapacitors into a soldering bath.
b) Keep the supercapacitor’s surface temperature at or below 100 oC for no more than 60 seconds (the peak 105 oC) when soldering. Please refer to the chart at right to set soldering conditons. It is recommended to check the supercapacitor temperature before you use.
