High power (low ESR) supercapacitors

To meet consumer demand for mobile devices with greater efficiency and functionality, Murata began focusing its R&D efforts on supercapacitors (EDLC*) in 2008, at which time we made a strategic decision to license leading-edge supercapacitor technology from CAP-XX Limited   [Cap-XX] , an Australia-based firm. Working from this collaborative basis, Murata has enhanced the design and manufacturer of these high power (low ESR) supercapacitors in a compact, slim package, and we continue our research efforts to develop even better and higher performing products.

*Supercapacitor is also known as "EDLC" in academic parlance. EDLC stands for Electrical Double Layer Capacitor. In addition, supercapacitor is abbreviated as "supercaps." All are different terms for the same kind of capacitor.

Murata offers two series of supercapacitors:

DMT Series

The general-purpose type DMT series is the world's thinnest supercapacitor, featuring wide operation temperature range and high reliabiilty for various applications.

DMF Series

The high-power type DMF series features low ESR and high capacitance in a small, slim package
