The Electric double layer capacitor has the main use of a Charge Reservoir. That means a large amount of electrical charge in a small footprint.
These charge/discharge quickly unlike the battery, There is no Electrical Energy to Chemical Energy Transformation and back, like in batteries. It may need caution in design and usage as they may [...]
Selecting the parts for your product design, choosing the components intelligently is a part of Product Design Engineering.
Budget, Availability, Size, Alternate Vendors, Product Life and Quantity to be manufactured are some factors that determine the selection of a prudent and experienced design professional.
To choose the right type of part, an exhuastive knowledge of the behaviour [...]
