Working Principle

A tantalum capacitor is a type of electrolytic capacitor which uses a layer of tantalum oxide as a solid electrolyte. It consists of two components: a cathode (anode) and an anode (cathode). The cathode is generally made of a tantalum pellet and the anode of a carbon or manganese dioxide paste. A thin layer of oxide forms on the tantalum pellet, which acts as the dielectric layer.

Current flow in a tantalum capacitor is just like any other type of capacitor; it is based on the principle of electrostatic capacitance. When a voltage is applied, charge particles (electrons and ions) flow between the two terminals. When the voltage is removed, the particles that have migrated to the anode remain in place, and the capacitor is “charged”. When a higher voltage is applied, the charge particles migrate back to the cathode, discharging the capacitor.

T86D157M004ESAS capacitors have a number of features which make them suitable for many applications. They are highly reliable, have a long life, high storage capacitance, and they are very resistant to electrical and thermal shock. They also have a very low ESR (equivalent series resistance) which makes them ideal for high frequency applications.
