PAS can store a large number of ions into its amorphous structure (doping), therefore PAS capacitor
has much larger capacitance than conventional electric double layer capacitors.
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. PAS capacitors are volume ratio 1/2-1/3 smaller
than conventional electric double layer capacitors. In addition, its low internal resistance enables to quick charge and
large current discharge. High capacitance type (LA series) is suitable for main power supply of electric accumulator of
solar cell, cordless devices and toys. Low ESR type (LR series) is mainly for assistant power supply to lengthen life-time
of main power supply and so on.
High capacitance
Quick Charge & Discharge
High reliability
Environmentally friendly
Low internal resistance and quick charge is possible with ampere measure.
Possible to charge/discharge more than 100,000 times with less deterioration caused by charging/discharging
compared to secondary battery, which involve chemical reaction, and enable to more than 100,000 times
charge/ discharge and large excellence of durability for over charge/discharge.
PAS capacitor is environmentally friendly power source, which does not contain any heavy metals such
as Cd and Hg. Moreover does not employ Pb on wire lead. (Lead-free compliant)
