Maxcap® double layer capacitors are a new electric energy storage device with:
Extremely high volumetric efficiency (over 5.5 farads/in³)
Virtually unlimited service life
Fast/charge discharge capability
Very low leakage current.
Wide operating temperature range, including -40°C to +85°C (LT & LJ Series)
A Maxcap DLC (commonly known as supercap or supercapacitor) 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 supported from several seconds to minutes.
Key Features
Very High Capacity in Small Size Up to 100 times that of conventional capacitors. Circuit board space and equipment size can be reduced.
Useful Voltage Ratings: 3.5 & 5.5 volt - Ideal for CMOS operating voltage range.11 volt - LV Series, backup for relays, actuators, small motors.
Full Range of Sizes From 0.01 to 5.6 farads @ 5.5 volts; 0.47, 1.0 & 5.0 farads @ 11 volts.
Low Profile With LP, LK & LJ series.
Ultra Long Life Unlike batteries, Maxcap LDCs have no parasitic chemical reactions. They can be fully charged and discharged indefinitely. There is no memory effect.
Maintenance Free Maxcap DLCs can be placed in remote locations and require no access ports. Warranty claims are minimized.
Nonpolar Assembly errors and costs are minimized.
Wide Operating Temperature Range -40 to +85°C LJ & LT Series; -25 to +70°C LP. LC, LK, LF, LV, LX Series
Simple, Low Cost Circuitry Since Maxcap DLCs do not require current limiting resistors or over-voltage protection, component costs and assembly time are reduced.
Safer Than Batteries These capacitors will not explode or be damaged if short circuited. They can be installed with wave soldering equipment or surface mount package with IR or vapor phase reflow equipment
