This shows the structural and material differences in Chemi-Con’s SMD (chip) type capacitors. Both aluminum electrolytic capacitors and conductive polymer aluminum solid capacitors have a similar structure. An aluminum foil is used for both the anode and cathode, and the dielectric material is alumina. The main difference is the electrolyte material. Contrary to aluminum electrolytic capacitors that employ liquid electrolyte, conductive polymer aluminum solid capacitors employ a solid conductive polymer electrolyte. The Proadlizer shown on the right, employs conductive polymer just like the PX/PS types, but possesses a flat-laminated structure with silver for cathode material.
