High-performance SMD electrolytic capacitor has low ESR and high ripple current, 24% dissipation factor. SMD aluminum electrolytic capacitors usually play the electrical functions of filtering, bypassing, coupling, decoupling, and switching.
Tips: What is Electrolytic Capacitor?
SMD electrolytic capacitors are usually made of metal foil (aluminum/ tantalum) as the positive electrode, and the insulating oxide layer of the metal foil (alumina/ tantalum pentoxide) as the dielectric. Electrolytic capacitors are divided into aluminum electrolytic capacitors and Tantalum Electrolytic Capacitors. The negative electrode of aluminum electrolytic capacitors consists of thin paper/film or electrolyte polymer soaked in an electrolyte (liquid electrolyte); the negative electrode of tantalum electrolytic capacitors is usually manganese dioxide. Electrolytic capacitors get their name because they all use electrolytes as negative electrodes (note the distinction from dielectrics).
