The Kemet T350E106K016AT is a 10 µF, 10%, 16 volt, radial lead tantalum capacitor. It offers the advantages of small size, low leakage, and low dissipation factor for filtering, bypass, AC coupling, and timing applications. The final electrolytic capacitor type is the niobium oxide electrolytic.
Tantalum capacitors are the other variety of electrolytic capacitors. These use manganese dioxide as their electrolyte, which is solid in its finished form. During production, manganese dioxide is dissolved in an acid, then electrochemically deposited (similar to electroplating) onto the surface of tantalum powder which is then sintered.
According to the different valve metal, the electrolytic capacitors can be divided into an AEC, a tantalum electrolytic capacitor, and a tantalum-niobium alloy electrolytic capacitor. Among them, the AEC is the focus of our attention, because it is currently the most widely used in the field of low-frequency AC line filtering electronic …

The plates are usually made out of materials like aluminium and copper, and the dielectric can be made out of materials like ceramic, plastic and paper. Capacitors can range in voltage, size and farads (F) of capacitance.
