Murata Manufacturing will showcase its latest electric double layer capacitor in the DMF series at the CEATEC JAPAN 2012 to be held from October 2 to 6, 2012 at Makuhari Messe in Chiba Prefecture.

The new product has the distinction of being the worldfs thinnest double layer capacitor. Murata will soon commence mass manufacture of the capacitors which are characterized by high power density and low resistance at the Fukui Murata Manufacturing facility from October of this year. The properties of the DMF electric double layer series of capacitors make them ideal for application in supplementary power supplies for LED flash units.
Electric double layer capacitors are compliant with the Restriction of Hazardous Substances Directive (RoHS) as they do not employ toxic substances like lead. The capacitors do not depend on chemical reactions for energy storage as they can adsorb the ions on active carbon surfaces. This feature enables the capacitors to rapidly charge and discharge.
Murata acquired the technology to manufacture the DME series of electric double layer capacitors by virtue of their partnership with Australian-based CAP-XX. The DMF series retains the resistance and power density properties of the DME series but is designed to be atleast 30% smaller than the DME capacitor series. The DMF series of capacitors operate in the temperature range of -30°C to +70°C. The devices allow high current, high output charging and discharging because of their low Equivalent Series Resistance (ESR) which is between 40 m W to 90 m W. The DMF capacitors offer a life cycle of 100,000 cycles when used in conjunction with other devices.
