SuperCapacitors | Pros & Cons | Why Choose a SuperCapacitor?

Capacitors or Double Layer Capacitors have rapidly become recognized, not only as an excellent compromise between “electronic” or “dielectric” capacitors such as ceramic, tantalum, film and aluminum electrolytic, and batteries, but also as a valuable technology for providing a unique combination of characteristics, particularly very high pulse power and capacitance densities.

SuperCapacitor Technology | EDLCs | Electrochemical Double-Layer

• Capacitance Values: 0.33F to 1000s of Farads
• Activated carbon amplifies the surface area A of the electrode
• d is defined by the diameter of the salt ion in the electrolyte
• Voltage, however, is now a function of temperature & voltage

Key Things to Know Before Selection

• Operating Temperature Range - Most Critical!!!
• Application: Energy Harvesting, Pulse Power, Power Hold-Up or Battery Replacement
• Importance of ESR and Leakage Current to the Design
• Operating Voltage
• Expected Life Time
• Cost Feasibility
