With the increasing popularity of the thin type note-book PC ( some PCs are designed in half size of current models, around 20 mm thick) in note-book PC market, capacitors to be used for smoothing circuits of power supply of note-book PCs have been required to be lower profile. To meet the market demand, Industrial Devices Company, Panasonic Corporation has succeeded in developing “ the conductive polymer aluminum electrolytic capacitor SP-Cap “, featuring lowest ESR and large capacitance in the industry in the shape of low profile (1.1 mm height, 1.4 mm height), and will commence mass-production.
