BestCap Ultra-low ESR High Power Pulse Supercapacitors
Super capacitors, (also referred to as Electrochemical 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 high energy, power and capacitance densities.
Based on a unique patented aqueous chemistry and an innovative design, the AVX’s BestCap series offers high capacitance, even with short pulse applications such as in GSM, GPRS, Edge and PCS based systems. BestCap technology makes this an ideal solution for any portable or wireless device requiring high power availability. The Low Profile versions are ideally suited to PCMCIA, PDA, DSC and similar applications.
Because BestCap, when used in parallel with a battery, provides a current pulse with a substantially higher voltage than that available just from a battery the efficiency of the RF power amplifier is improved. Additionally, the higher-than battery voltage supplied by the BestCap® keeps the voltage pulse above the “cut off voltage” limit for a significantly longer time than is the case for the battery alone.
