*We changed the product name from "Electrical Double Layer Capacitor (EDLC)" to "Supercapacitor" in April 2015.
Murata Manufacturing Co., Ltd. today announced the launch of its DMT series, one of the most reliable electrical double-layer capacitors (EDLC) available on the market today. The solution offers superior long-term, high temperature reliability (five years at 70°C) , a maximum operating temperature of 85°C, low resistance (130mΩ of high-current, high-output charging and discharging) , a nominal capacitance range of 470mF, and an innovative design that enables high voltage handling (4.2V) . Measuring 14 x 21mm with a thickness of just 3.5mm, the DMT series is ideally suited for applications such as solid state drive (SSD) and communication system backup, power assistance for smart meters, and energy-harvesting devices.
- Long-term reliability of five years at 70°C
- Low ESR (equivalent series resistance) of 130mΩ enables high-current, high-output charging and discharging
- Innovative internal structure design enables high voltage operation
- SSD backup
- Power assistance for smart meters
- Backup power supply for communication systems
- Backup power supply for other systems
- Energy storage device for energy-harvesting systems
The expansion of these markets is driving the demand for smaller, thinner, and low-resistance capacitors that assure high reliability in the event of power failures. For example, since an increasing number of end products are being used outdoors (e.g., smart meters) , there is a heightened focus on ensuring that solutions have exceptional dependability. Coupled with more miniaturized features, design engineers now require products that are both extremely advanced and eco-friendly.
The basis behind this technology is the result of the company's collaboration with CAP-XX. In order to meet demand for devices with greater efficiency and functionality, Murata strategically acquired supercap technology from CAP-XX in 2008. Murata's focus on EDLC research and development, coupled with CAP-XX's market expertise, drives the advancement of enhanced EDLC design.
