Tantalum Capacitors

Tantalum capacitors are based on the separation of conductive particles with an insulating layer using the principle of electrochemical capacitance. They are often referred to as “tantalum electrolytic capacitors” because of their reliance on electrolyte in the dielectric material. This makes them one of the most popular types of capacitors used in modern electronics.

M39003/01-2312/TR Application Field and Working Principle

M39003/01-2312/TR tantalum capacitors are commonly used for a variety of applications in the electronics industry. These capacitors are small, low-voltage, high-value components perfect for use in filter circuits, which are used to remove noise or ripple from a signal. They are also used in the stabilization of power supplies, in which case they absorb energy, which helps to regulate voltage outputs, or act as a buffer to reduce the sudden changes in electrical input. Additionally, they provide signal filtering in these applications.

The working principle of M39003/01-2312/TR tantalum capacitors is as follows. Copper electrodes are soldered to both ends of the capacitor body. An electrolyte solution is then applied to the capacitor body, which acts as an insulating medium. This creates an electric double layer at the electrodes, which acts as a barrier to electric current. When a voltage is applied to the capacitor, electric current from the anode electrode is attracted to the cathode, forming an electrical diaphragm. This formation of an electric double layer and the creation of an electric diaphragm result in the operation of the capacitor.

M39003/01-2312/TR tantalum capacitors have a number of advantages, such as high capacitance, low impedance, low current leakage, small size, low cost, and manufactured ease. Having said that, they are also subject to some drawbacks, notably their limited maximum operating voltage and temperature, and their susceptibility to the “dielectric absorption” phenomenon. Nonetheless, these devices continue to be in demand and are widely used in modern electronic applications.
