Supercaps provide memory backup for critical systems

Lincolnwood, Ill. — Illinois Capacitor has introduced the DC Series of coin cell style supercapacitors that can 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, said the company.

The DC Series, available in three case configurations for horizontal, vertical and center-lead mounting, offers numerous values and lead combinations with case sizes as small as 6.8 x 4.6 mm. The operating temperature ranges from -40 deg C to +85 deg C and 90-95% relative humidity. Other features include very fast charge/discharge cycling, IEC 62391 and RoHS compliance, and low equivalent series resistance (ESR).
DC Series capacitors are ready to board mount in applications such 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 reduce board size and case requirements, said Illinois Capacitor.
