High-Reliability Supercapacitor operates from -30 to +85°C.

Press Release Summary:

Supplied in 20.5 x 18.5 mm footprint package, DMG series utilizes active carbon technology and provides high-power backup. Each electrical double-layer capacitor (EDLC) achieves high reliability with 5-year life span at 70°C. With 1.4 mm profile, 2.1 V single-cell option provides nominal capacity of 700 mF and ESR at 1 kHz, 70 mW. Double-cell option (4.2 V) has 2.8 mm profile and nominal capacity of 350 mF and ESR at 1 kHz, 130 mW.

Original Press Release:

High Reliability EDLC Supercapacitor Ideal for Extended Temperature Long-Life Applications

Hoofddorp, Netherlands: Murata today announced the addition of the DMG series to the company's line of thin, low-resistance, electrical double-layer capacitors (EDLCs). The DMG supercapacitors, which provide high power back-up, achieve high reliability with a five-year life span at 70 degrees C, making them an ideal choice for enterprise solid state drive (SSD) manufacturers and telecom "last gasp" applications. Smart meters are also a key application for the DMG series as the full operating temperature range is - 30 degrees C to + 85 degrees C.

Murata's DMG series offers high voltage with very low equivalent series resistance (ESR) all within a miniaturized, yet robust package. Available in 2.1 V single-cell and 4.2 V double-cell options, the 2.1 V provides a nominal capacity of 700 mF with a profile of only 1.4 mm and an ESR at 1 kHz 70 mW. The 4.2 V device has a nominal capacity of 350 mF at 2.8 mm thickness and 130 mW ESR at 1 kHz.

The innovation behind Murata's high performance DMG EDLC is based on active carbon technology. Unlike traditional energy storage devices, the carbon, which is used as an electrode, without employing a chemical reaction, leads to the longer life cycle. Also, the capacitance is directly related to the surface area of the active carbon, giving the DMG series high capacitance values in a small and low profile design. Measuring only 20.5 mm x 18.5 mm x 1.4 mm, which leads the industry in compact packaging, Murata's EDLC series is designed for extended temperature applications.

Supercapacitors play a role in energy conservation applications, from memory backup in home appliances, mobile phones, information devices, and energy harvesting storage systems.

The basis behind this new technology is the result of Murata's collaborations with CAP-XX. In order to meet consumer demand for mobile devices with greater efficiency and functionality, Murata strategically acquired leading edge super cap technology from CAP-XX in 2008. Since then, Murata's focus on EDLC research and development, coupled with CAP-XX's expertise, has lead to the maturity of the enhanced EDLC design.
