Murata DMT / DMF Series EDLCs

Murata Electrical Double-Layer Capacitors (EDLCs) offer much higher energy storage and power density than any existing conventional capacitor technology.  These features make Murata's EDLCs ideal for applications requiring burst or pulse loads like LED flash, audio circuits, and power amplifiers. They are also ideal for smart meters or backup application for SSD.

Murata DMT Series Electrical Double-Layer Capacitors are high temperature EDLCs that offer long-term reliability of five years at 70ºC and wide operating temperature range from -30ºC to +85ºC. The DMT Series EDLCs from Murata have 4.2 voltage (constant) and 470mF capacitance, in addition to low ESR (130mΩ), low leakage current, and compact and slim design (21.0mm x 14.0mm x 3.5mm). As the newest addition to Murata's EDLC product line that delivers much higher energy storage and power density than any existing conventional capacitor technology, the highly reliable DMT Series exhibits a long life cycle exceeding 100k cycles.

Murata DMF Electrical Double Layer Capacitor (EDLC) delivers high capacitance and low ESR in a small, slim package. The DMF EDLCs from Murata measure 2.5mm and 3.2mm in thickness, with capacitance of 330mF and 470mF and maximum working voltage of 5.5V. This supercapacitor offers 40 - 60mOhms ESR and stable temperature characteristics, enabling it to be charged and discharged frequently over the operating range of -30ºC to +70ºC. The DMF EDLC has the highest power density levels available in the industry, making it ideal for use as an auxiliary power source in LED flash units, digital cameras, and cell phones. Combining the DMF capacitor with various power devices provides a life cycle of 100,000 cycles or more and enables it to be used as a maintenance-free power storage element.
