BestCap®: A New Generation of Low Voltage, Low ESR, Pulse, Double Layer Capacitors
Written By: Lee Shinaberger | Bharat Rawal | Chris Reynolds

Abstract:
Electrochemical double layer capacitors (EDLCs) produced for back up applications in the last twenty-five years had high Equivalent Series Resistance (ESR) and high loss of capacitance when used in pulse power applications. In addition, the voltages of these devices were limited to less than 5 volts. In 2000, AVX introduced the BestCap® line of capacitors to address these limitations to serve the high pulse power market. This paper will present capabilities and subsequent improvements to the BestCap® product line.
