PAS(Polyacenic Semiconductor), which has been originally developed
by Shoei Electronics is a kind of conductive polymers synthesized
through pyrolytic treatment of phenolic resin. PAS capacitors, in which
PAS is employed for both positive and negative electrodes, show
extremely high performance.
What is PAS ?
Molecular structure of PAS
High capacity / High reliability
PAS can store a large number of ions into its amorphous
structure (doping), therefore PAS capacitor has much
larger capacity than conventional electric double layer
capacitor. In addition, PAS is extremely stable material
and PAS capacitor shows excellent performance of cycle
life and durability to overcharge and overdischarge.

RoHS / WEEE compliance
PAS capacitors are RoHS and WEEE compliant products
and have no recycling and collection duty that is required
in lithium ion batterys case.
The worlds smallest capacitor
PAS311 series is the worlds smallest coin shaped capaci-
