Unlike traditional supercapacitors, the BestCap does not face the limitations of high ESR in the tens of Ohms range and/or high capacitance loss when required to supply very short duration current pulses. The low ESR BestCap is a perfect fit in applications where the energy source is a primary rechargeable battery and large pulse power requirements are needed. They provide high-pulse capability in a low profile package while maintaining higher voltage across the battery.
AVX's unique BestCap technology provides excellent high-power pulse characteristics based upon a combination of very high capacitance and ultra-low ESR, together with extremely low leakage current. Using a patented aqueous chemistry and innovative design, this series offers high capacitance, even with the shortest of pulse applications.
