Tantalum Capacitors - T95R397M6R3EZAL

Tantalum capacitors are a special form of electrochemical capacitor consisting of a porous tantalum anode covered in a barrier oxide layer. This layer acts as the dielectric material of the capacitor. A cathode, which is typically made of a metal or conductive plastic, is attached to the tantalum anode, thereby forming the inner electrical junction of the capacitor. The physical construction of tantalum capacitors makes them unique and well suited for many applications due to their low equivalent series resistance and their smaller size when compared to aluminum electrolytic capacitors.

Application field

T95R397M6R3EZAL is a high-performance chip tantalum capacitor, its high capacitance and small size make it the ideal solution for high-density surface mount applications. It provides superior high frequency and high temperature performance. It is typically used in telecommunications, cellular infrastructure, audio and video equipment, and networking systems. Other applications include medical instrumentation, military electronics, and alternative energy equipment.

Working Principle

The working principle of a tantalum capacitor is similar to that of an electrolytic capacitor, except that tantalum is used as the dielectric material instead of aluminum. As previously mentioned, a porous tantalum anode is coated in a specialized oxide layer known as the dielectric barrier layer. When a capacitor is charged, electrons begin to accumulate in the dielectric material. This creates an electric field that drives the dielectric material to the point of conduction. At this point, the electrons can move freely, creating a stable voltage.

The dielectric material itself works to reduce the risk of short circuits by preventing electrical breakdowns. Additionally, the dielectric material helps reduce the amount of current leakage and self-heating that can occur with other types of capacitors. As a result, tantalum capacitors are able to provide a stable voltage over a wider temperature range than other capacitor types.
