Supercapacitor provides high voltage and high energy density

23-10-2020 | New Yorker Electronics | Passives

New Yorker Electronics has released the new Cornell Dubilier DSF Series of high voltage and high energy density supercapacitors. The devices also offer greater power density, low ESR, particularly low self-discharge rate and ultra-fast charging. Applications for this new device comprise green energy, backup power, IIoT and small EVs.

Supplied under the Illinois Capacitor brand, devices provide a notable jump in voltage rating over typical supercapacitors, to 3WVDC for a single component and 6WVDC for a dual-pack device. This higher voltage spec produces greater energy densities, which saves space and can lessen the number of devices needed.

The series comprises 17 different value/voltage combinations, ranging in capacitance from 1.5F to 600F, with voltage ratings from 3WVDC to 6WVDC. Multiple devices are able to be banked in series or parallel for even higher voltage or capacitance. ESR varies by part but is lower than many capacitors with similar storage abilities. With an operating temperature range of -40C to 85C @ 2.5V (-40C to +65C @ 3V), the DSF is tolerant of wide-ranging operational environments.

Typical applications for the devices include solar and wind energy harvesting, mechanical actuators, AGV, EV transportation power, smart utility meters, pulse battery pack alternatives, battery/capacitor hybrids, memory backup, UPS systems, emergency lighting, LED power, solar lighting or anywhere that substantial energy storage is required.
