Maxcap® Double-Layer Capacitors

Ohmite Maxcap® Double-Layer Capacitors (DLCs) are high-energy-density capacitors for memory backup and data-transmission power. Ohmite Maxcap Double-Layer Capacitors offer high volumetric efficiency (over 5F/in3), virtually unlimited service life, fast charge and discharge capability, and low leakage current. A Maxcap DLC, the size of a thimble, supports µA data retention currents of CMOS RAMs for up to several weeks. Microprocessors, small motors, and activators with current requirements from one to several hundred mA can be supported from several seconds to minutes. Maxcap DLCs never need replacing; they do not undergo irreversible chemical reactions. Unlike aluminum electrolytic capacitors, they do not experience dry-up problems.
