Supercapacitors Provide Memory Backup For Critical CircuitsThe DC Series of Coin Cell Style Supercapacitors from Illinois Capacitor provide on-board memory backup at much longer life spans than batteries. With 0.15 to 8 Farads of capacity, at voltages up to 5.5 WVDC, these devices can supply sufficient power to prevent loss of data during a power interruption. This is as much as five times the capacitance of some other coin type supercapacitors or ultracapacitors. They are available in three case configurations for horizontal, vertical, and center-lead mounting.

The DC Series includes numerous values and lead combinations with case sizes as small as 6.8 x 4.6 mm. Operating temperature ranges from -40 to 85°C and 90-95% relative humidity. Other features include very fast charge/discharge cycling, IEC 62391 and RoHS compliance, and low ESR.
