This course has shown that only four basic parameters are required for an initial supercapacitor selection. In addition to these four parameters only operating temperature range and life issues need to be taken into account to make a reliable product selection. The effects of leakage current have also been addressed, specifically relating to the time required to accurately measure this parameter and its role in causing voltage imbalance in series connected supercapacitors. Finally, we have introduced our on-line calculator spreadsheet to assist with your product selection needs.
