Three-cell devices offer greater energy potential and power output than single or dual-cell parts

Knowles' Cornell Dubilier brand has announced its latest EDLC modules, or supercapacitor modules, are now available through New Yorker Electronics. Based on Knowles' Cornell Dubilier brand DGH and DSF Series supercapacitors, these cutting-edge capacitors use a three-cell package for higher operating voltages and space savings.

Like other supercapacitors the brand offers, the new devices provide very fast power discharge that conventional capacitors or batteries cannot match.

That large capacity makes it feasible to support brief power interruptions, supplement batteries, or even be used in place of batteries in many applications. These supercapacitors are excellent for applications including solar and wind energy harvesting, mechanical actuators, AGV, EV transportation power, smart utility meters, IoT, pulse battery pack alternatives, memory backup, battery/capacitor hybrids, UPS systems, emergency lighting, LED power, solar lighting or anywhere that significant energy storage is needed.

The new supercapacitors offer a notable jump in voltage rating over typical radial-mount supercapacitors, up to 9WVDC. The unique three-cell radial-leaded package is a key feature of the DGH and DSF series additions. Compared to single- or dual-cell supercapacitors, the compact design saves space and permits much higher operating voltages, making them excellent for a wider range of applications. Both series include capacitance values from 0.33 to 5 Farads. Multiple devices can be banked for even higher capacitance or voltage.

Their internal cell balancing provides optimal performance and saves production time. The series' three-cell supercapacitors are also more cost-effective than other options currently available.

Both series deliver high energy density and extremely low self-discharge rates from a performance standpoint, benefiting energy storage applications. They also tolerate wide-ranging operational environments, with operating temperature ranges from -40C to +65C for DGH 8.1V/DSF 9V and -40C to +85C for DGH 6.9V/DSF 7.5V. Low ESR minimises energy loss for high efficiency. ESR varies by part but is lower than most capacitors with similar storage capabilities. These supercapacitors are designed to withstand over 500,000 charge/discharge cycles, ensuring long-lasting performance without performance degradation. Operating life is expected to be up to ten years.
