AVX BestCap® series

In the BestCap®, a unique proton polymer membrane is used – charge transfer by protons is close to the transfer rate for electrons and orders of magnitude greater than organic molecules. BestCap® is a low ESR pulse super-capacitor based on the non-hazardous proton activated polymer system. It competes directly with devices made with organic electrolytes, but has a far wider voltage range, from 3.6V to 20V (organics are typically limited up to 5V). BestCap® has a temperature range of -20°C to +70°C, which is wider than for batteries, and also offers select values available between -40°C to +75°C. BestCap® has the most “capacitor-like” frequency response of all supercaps and has low ESR and low profile characteristics.
