BESTCAP®: A NEW GENERATION OF PULSE DOUBLE LAYER CAPACITORS
BestCap®, a new generation of Double Layer Capacitors(DLCs) have been developed to deliver low ESR, high power pulses, or provide back-up power in some applications. These capacitors have values of 10 to 560 mF, voltage ratings of 3.5 to 12 volts and ESR values of 20 to 500 mW.
This paper describes the electrical properties of the BestCap®and it's endurance under different environmental conditions. Specific applications are shown for illustrative purposes.
Double Layer Capacitors (DLCs), also known as electrochemical or supercapacitors, have been produced in the last twenty-five years as an excellent compromise between batteries and electronic or dielectric capacitors such as ceramic, tantalum or film capacitors. In general, these DLCs have high Equivalent Series Resistance (ESR) and high loss of capacitance when used in pulse power applications.
BestCap® capacitors, a new generation of low ESR DLCs,have successfully addressed these two limitations (high ESR and loss of capacitance in the kHz frequency range) by utilizing proton conducting polymer separators, nano-particle carbon electrodes, unique current collectors and other design features. In this paper parameters of these BestCap® devices will be presented, results of reliability testing will be shown and a few applications will be outlined.
