This document introduces AVX BestCap® Ultra-low ESR High Power Pulse Supercapacitors, including product overview, electrical ratings, mechanical specifications, etc.
The BestCap® series from AVX offers ultra‑low equivalent series resistance (ESR) and high capacitance, delivering high‑power pulse capability for portable and wireless devices such as GSM, GPRS, and PCMCIA applications. The technology uses a patented aqueous chemistry and a proton‑conducting polymer membrane to achieve fast charge transfer and minimal voltage drop during short pulses.
The document lists detailed electrical ratings, mechanical dimensions, case configurations, packaging quantities, mounting procedures, and application notes. It includes tables of capacitance, voltage, ESR, and leakage for each case size and lead style, as well as guidance on series‑parallel combinations and ordering instructions.
