Supercaps handle wide temperature variations

22 August 2012 Passive Components

Murata 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 backup, achieve high reliability with a five-year life span at 70°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°C to +85°C.

The capacitors offer high voltage with very low equivalent series resistance (ESR) all within a miniaturised 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 of 70 m. The 4,2 V device has a nominal capacity of 350 mF at 2,8 mm thickness and 130 m ESR at 1 kHz.

The innovation behind Murata’s 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.
