The ESR in a tantalum capacitor is a culmination of the resistivities associated with the contact of each capacitive element within the capacitor structure. The basis of the structure is an extremely porous pellet of pressed tantalum particles that are sintered in a vacuum to enhance the contact areas between these particles. The cathode contact is the deposited MnO2 material, which snakes through the channels in the extremely porous structure from the outside surface to the depth of the pellet… CONTINUE READING
