High peak current electrical double-layer capacitors offer low ESR in 2.5mm slim package

January 10, 2013 // By Julien Happich
Murata's EDLC series of high peak current electrical double-layer capacitors has a profile of 2.5mm±0.2mm and features a low equivalent series resistance from 40mΩ to 60mΩ while being stable in temperatures.

The capacitors can be charged and discharged frequently over the operating range of -30 to +70°C. Initially, the DMF EDLC series will offer 330mF and 470mF capacitance values to support various energy requirement demands. Package thickness ranges from 2.5mm±0.2mm to 3.2mm ± 0.2mm and all products in the series provide an instantaneous maximum working voltage of 5.5V. The slim DMF series features the highest power density levels available on the market, making the advanced supercapacitors suitable for use as an auxiliary power source in LED flash units, digital cameras and cell phones. Additional applications include peak load assist for GSM PA’s, smart meters, compact motor starters, and USB power bus. The new EDLC series provides an optimized internal configuration to improve energy and power density. In addition, the DMF series offers a simplified, inline terminal configuration that optimizes board space. The low ESR allows for high output current with quick charge and discharge characteristics.
