The Battery Energy Saving Technology Capacitor (BestCap) series of electromechanical supercapacitors from AVX Corp. offers an ESR between 25 milliohms and 350 milliohms to minimize instantaneous voltage drops.

The BestCap capacitors are capable of storing several hundred times as much energy as conventional aluminum electrolytic capacitors, and delivering energy at more than 10x the discharge rate. Applications include wireless telecom, memory back-up, wireless alarm systems, hybrid battery packs, automatic meter reading systems, and mainframe computer decoupling.

The supercapacitors are available with capacitance values of 22mF to 560mF with voltage ratings of 3.5-, 5.5-, 7-, 9-, and 12V. Maximum leakage current is between 5?A to 40?A, depending on the size. Package options include footprints of 28-by-17mm and 48-by-30mm with a profile down to 2.1mm.
