Foil tantalum capacitors are constructed by rolling up two thin foil strips, detached by a paper which is concentrated (saturated) with electrolyte, into a convolute roll. The tantalum foil (which acts as an anode) is chemically inscribed in order to stepup its effective surface area, therefore offering more capacitance in an available volume.
