Molecular structure of PAS

“PAS311 series”is the world’s smallest coin shaped capaci-

tors, which size is diameter 3.8mm × height 1.1mm.

This smallest product was carried out by developing

electrode materials, sealing technology and introducing

special processed heat resistance gasket.

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.

PAS capacitors are RoHS and WEEE compliant products

and have no recycling and collection duty that is required

in lithium ion battery’s case.

What is PAS …?

PAS(

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.
