Coin Cell Style Supercapacitors from Illinois Capacitor Provide Memory Backup for Critical Circuits

The 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 8F of capacity, at voltages up to 5.5 WVdc these devices can supply sufficient power to prevent loss of data during a power interruption. According to the company, this is as much as five times the capacitance of some other coin type supercapacitors or ultracapacitors. The units 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 4.6mm. 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.

DC Series capacitors are ready to board mount in such applications as smart meters, HVAC controls, building automation, business phone systems, appliances, instruments and other microprocessor-based devices. Because of their high power density, they can help to reduce board size and case requirements.

DC Series Film Capacitors are available from stock. Prices in 1,000 lot quantities start at: $0.55.
