Double layer capacitors up to 3000 F

23 July 2008 Passive Components

WIMA is supplying double layer capacitors with capacitances up to 3000 Farads, suitable for energy storage requiring charge or discharge of high loads in a short interval. They are available as SuperCap C with cylindrical case or as SuperCap R with rectangular case.

SuperCaps are cascaded to so-called modules to meet the operating voltage required by the application. Compared to conventional battery or charger solutions, they are maintenance free and are relatively low in weight, making them suitable for use in isolated systems, eg, inaccessible areas, since they are also resistant to high temperature changes.

Due to their low ESR, SuperCaps can be loaded with very high currents for a short time. Damage by overload is not a concern, as long as the permissible cell voltage is observed. When properly handled, a lifetime of more than 10 years can be achieved. Due to the capacitor construction, a SuperCap can be loaded with more than 500 000 charge/discharge cycles with a power efficiency of more than 90%.

Typical applications are in slip control units of major wind power plants, for micro-turbine starters, for speeding of fuel cells, starting of large V16 or V24 cylinder motors of railway or vessel drives, energy storage in conjunction with photovoltaic units or for recuperation of braking energy in the automotive field.
