The three-cell devices are said to offer greater energy potential and power output than single or dual-cell parts.

CAZENOVIA, N.Y.—Knowles Precision Devices reported that its latest Electric Double Layer Capacitor (EDLC), or supercapacitor, modules are now available. The capacitors, based on Knowles’ Cornell Dubilier brand DGH and DSF Series supercapacitors, use a three-cell package for higher operating voltages and printed circuit board space savings, the company said in a release.

Knowles Precision Devices is a segment of Knowles Corporation, a major global supplier of high-performance components. Knowles Corporation acquired Cornell Dubilier in 2023 to expand its offering of high-quality film, electrolytic, and mica capacitors.

The new devices are reported to provide “very fast power discharge” versus conventional capacitors or batteries. That large capacity makes it possible to support brief power interruptions, supplement batteries, or even be used in place of batteries in many applications.

The supercapacitors are well-suited for applications that include solar and wind energy harvesting, mechanical actuators, automated guided vehicles (AGV), EV transportation power, and smart utility meters. Applications are also reported to include IoT, pulse battery pack alternatives, memory backup, battery/capacitor hybrids, UPS systems, emergency lighting, LED power, solar lighting, or applications that require significant energy storage.

According to the release, the new supercapacitors offer a notable jump in voltage rating—up to  9.0 WVDC—over typical radial-mount supercapacitors. A key feature of the DGH and DSF Series additions is the unique three-cell radial-leaded package. Compared to single or dual-cell supercapacitors, the compact design is said to save space and allow for “much higher operating voltages.”

Both series include capacitance values from 0.33 to 5 Farads. Multiple devices can be banked for even higher capacitance or voltage, the company said.
