High voltage, high energy density supercapacitor released by New Yorker Electronics

19 October 2020

New Yorker Electronics has released the new Cornell Dubilier DSF series of high voltage and high energy density supercapacitors. The DSF supercapacitors provide greater power density, extremely low self-discharge rate, low equivalent series resistance (ESR) and ultra-fast charging. Applications for this new device include green energy, backup power, industrial internet of things (IIoT) and small electric vehicles (EVs).

Released under the Illinois Capacitor brand, DSF supercapacitors offer a notable jump in voltage rating over typical supercapacitors, to 3.0 W V DC for a single component and 6.0 W V DC 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 F (Farad) to 600 F, with voltage ratings from 3.0 to 6 W V DC. Multiple devices can be banked in series or parallel for even higher voltage or capacitance. ESR varies by part but is lower than most capacitors with similar storage Source: New Yorker ElectronicsSource: New Yorker Electronicscapabilities. 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 tolerant 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.

Specific applications for DSF supercapacitors include solar and wind energy harvesting, mechanical actuators, AGV (automated guided vehicles), EV transportation power, smart utility meters, 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.

Depending on voltage and capacitance, there are four-lead configurations available. These are radial, two-pin snap-in, four-pin snap-in and radial dual pack. Case diameters and configurations vary. Custom modules, with active or passive balancing, are also available to meet higher voltage or capacitance requirements.
