Coin-Style Supercapacitors Provide Memory Backup for Critical Circuits
Tue, 03/15/2011 - 12:50pm
The DC Series of Coin Cell Style Supercapacitors from Illinois Capacitor provide on-board memory backup at long life spans. With 0.15 F to 8 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, according to the company. The devices 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. The operating temperature ranges from -40°C to +85°C and 90-95 percent relative humidity. Other features include very fast charge/discharge cycling, IEC 62391 and RoHS compliance and low ESR.
