Working Principle

T491C685M016AS tantalum capacitor is an electrolytic capacitor with low leakage current. Its working principle is similar to that of general electrolytic capacitors, but the composition is different. It is made of tantalum metal with an oxide dielectric layer on its surface. A metal electrode, usually manganese dioxide, is attached to the oxide to form a structure resembling a sandwich. The two metal plates in the capacitor are connected to the two external electric terminals, which establish an electric field across the oxide layer, separating the positively charged ions and the negatively charged electrons.

When the two contacts are connected to a circuit, a current flows through the contacts. A voltage greater than the work voltage of the oxide layer is applied to the anode and a voltage less than the work voltage is applied to the cathode. When a current is applied to the contacts of the tantalum capacitor, an electric field is also generated across the oxide layer. The electric field causes the electrons of the oxide to move toward the cathode and the positively charged ions to move toward the anode, thereby storing the charge in the capacitor.
