Murata Manufacturing Co. Ltd., has expanded its EDLC DMF series line of electrical double layer capacitors with the addition of the 1,000 mF DMF series with low ESR. The capacitors can be used as an auxiliary power supply for peak power assist or backup function. They provide longer life than batteries with energy storage devices with higher capacitance than what is found in conventional capacitors.
Rated voltage is 5.5 V (peak) and 4.2 V (constant), nominal capacitance is 1000 mF, ESR @ 1 MHz is 40 mΩ. The capacitor measures 14 x 30 mm and is 3.7 mm thick. Operating temperature range is -40 to +70 °C.
