Murata DMD / DME Series EDLC Supercapacitors

Murata DMD and DME Series EDLC Supercapacitors feature low-resistance and high capacitance in a thin package. Utilizing the phenomenon of storing charge in an electrical double layer (electrical double-layer capacitors) rather than traditional dielectric layers, the DMD and DME supercapacitors deliver high voltage with very low equivalent series resistance (ESR) over a wide temperature range. Because these EDLCs offer much higher energy storage and power density, they are ideal for applications requiring burst or pulse loads, such as LED flash, audio circuits, and power amplifiers, as well as battery assist in Smart Meters and POS, and for high power back-up for SSD (solid state drives).

Unlike a ceramic or aluminum electrolytic capacitor, the EDLCs (or supercapacitors) offer energy storage with high power density characteristics up to 1,000 times greater. Suitable for use with large current or high power for backup or peak power, nominal capacitance is measured at 100mA. Read more technical information...

Murata's high performance EDLCs are small and slim, single or double cell, and tested to -30ºC to 70ºC with little capacitance change. Read more about product performance and characteristics...

The trend towards small, well-designed, and feature-rich electronic devices is driving innovations across teh whole electronics industry. Murata's EDLCs are the result of recent advances in capacitor technology. Learn more from the audio/visual tutorial...
