Watch: These supercapacitors operate at higher voltages
Cornell Dubilier has unveiled a new series of higher voltage and high energy density supercapacitors under the Illinois Capacitor brand. DSF Supercapacitors offer a notable jump in voltage rating over typical supercapacitors to 3.0 working voltage DC (WVDC) for a single component and 6.0 WVDC for a dual-pack device. This higher voltage spec results in greater energy densities, which in turn saves space and may reduce the number of devices required.
The DSF Series includes 17 different value/voltage combinations, ranging in capacitance from 1.5 Farad (F) to 600 F, with voltage ratings from 3.0 to 6 WVDC. Multiple devices can be banked in series or parallel for even higher voltage or capacitance.
Equivalent series resistance varies by part but is lower than most capacitors with similar storage capabilities. With an operating temperature range of -40° C to 85° C at 2.5 V (-40° C to 65° C at 3.0 V), the DSF is Source: Cornell Dubiliertolerant of wide-ranging operational environments.
Like other supercapacitors offered under the Illinois Capacitor brand, the DSF Series gives engineers increased design options while holding down costs. With increased energy storage, supercapacitors can provide instantaneous bursts of power that cannot be matched by conventional capacitors. That capacity makes it possible to smooth brief power interruptions, supplement batteries, or even be used in place of batteries in certain applications.
Unlike batteries, DSF supercapacitors do not degrade with each cycle and are rated at 500,000 cycles. Operating life is expected to be up to 10 years. Applications for DSF supercapacitors include solar and wind energy harvesting, mechanical actuators, automated guided vehicles, electric vehicle transportation power, smart utility meters, the industrial internet of things, 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.
