SMD ceramic capacitors
Ceramic capacitors: made up of a ceramic insulator with two terminals sprayed with silver then sintered. On SMD capacitors, C.CAP stands for ceramic capacitors.
Aluminum electrolytic capacitors: made up of an aluminum cylinder filled with liquid electrolyte (together as the negative electrode) and a curly aluminum strip (as the positive electrode) covered with an oxide film (as the insulator) plugged in it.
Tantalum electrolytic capacitors: made up of tantalum or niobium (as the positive electrode) and dilute sulfuric acid (as the negative electrode), the oxide film covered on tantalum or niobium as the insulator. TAN.CAP or TC stands for tantalum capacitors.
