The LJ055474A from Ohmite Manufacturing is an Electric Double Layer Capacitor that is ideal for CMOS; RAMs, microprocessors, home appliances, utility meters, personal computers, energy management controls, thermostats, point-of-sale terminals, process controllers, and routers applications. It has a capacitance of 0.47 F and a capacitance tolerance from -20% to +80%. This supercapacitor has a voltage rating of 5.5 V and an equivalent series resistance (ESR) of less than 6.5 milli-ohms.

This capacitor provides exceptional energy capacity in a compact form factor, with an energy density that is 100 times greater than conventional capacitors. It features very long life since the capacitor lacks parasitic chemical reactions, enabling it to be fully charged and discharged indefinitely without any memory effect. This capacitor is available in a through-hole package that measures 16.5 x 13 mm.
