Maxcap Series

Double Layer Capacitors

Maxcap® double layer capacitors are a new electric

energy storage device with extremely high volumet-

ric efficiency (over five farads/in3), virtually unlim-

ited service life, fast charge/discharge capability and

very low leakage current.

A Maxcap DLC the size of a thimble will support

microamp data retention currents of CMOS RAMs

for up to several weeks, Microprocessors, small

motors and activators having current requirements

from one to several hundred milliamps can be sup-

ported from several seconds to minutes.

Conventional energy storage devices such as

batteries and aluminum electrolytic capacitors

often must be replaced during the life of a product.

Maxcap DLCs never need replacing because, unlike

batteries, they do not undergo life-limiting, irrevers-

ible, chemical reactions, and, unlike aluminum elec-

trolytic capacitors, they do not experience dry-up

problems.

The high capacitance of Maxcap DLCs results

from an electric double layer formed at the inter-

face of high surface area activated carbon and a

stable electrolyte. Unit cells are formed by separat-

ing two carbon/electrolyte wafers with an ionically

conductive porous separator and sandwiching them

between two electrically conductive, ionically imper-

meable membranes. The unit cells are stacked in

series to achieve the desired capacitor voltage.

CAUTION: Due to their relatively high internal

resistance, Maxcap DLCs should not be subjected to

large ripple currents.

F e at u r e S
