CDE Illinois Capacitor’s DGH Supercapacitor Series have been expanded up to 600 Farads.

The low-ESR, low-cost DGH Series, available from New Yorker Electronics, includes 24 different value/voltage combinations, ranging in capacitance from 0.5F (Farad) to 600F, with voltage ratings from 2.7 to 5.5WVDC.

The rated operating temperature range of the series is -40°C to 65°C at maximum WVDC, or from -40°C to 85°C at 2.3 Volts.

Multiple devices can be banked in parallel or series for even higher voltage or capacitance.

Because of their massive energy storage, DGH supercaps can discharge instantaneous bursts of power to smooth power interruptions, supplement batteries, or even be used in place of batteries in certain applications.

Unlike batteries, DGH supercaps from New Yorker Electronics do not degrade with each cycle.

At 2.7 Volts, operating life is rated at 10 years with 500,000 charge/discharge cycles.

Applications for these supercapacitors include: energy harvesting, IoT systems, mechanical actuators, transportation power, smart electric meters, pulse battery pack alternatives, memory backup, battery/capacitor hybrids, UPS systems, emergency lighting, LED power, solar lighting and many other devices requiring maximum energy storage in a minimum of space.

Radial, two-pin snap-in, four-pin snap-in, and dual pack configurations in the series are available, depending on voltage and capacitance combinations.

Likewise, case diameters and configurations vary, depending on values.

Parts are also fully RoHS compliant.

Custom modules, with active or passive balancing, are also available through New Yorker Electronics, combining multiple capacitors for higher voltage or capacitance specifications.
