Tantallum - Polymer Capacitors

Tantallum - Polymer Capacitors are widely used in consumer electronics, automotive and industrial applications, and various other fields. T540D226M030DT8705 is a type of tantalum-polymer capacitor, with the characteristics of small size, high reliability and long service life.

Application Field

T540D226M030DT8705 can be used in various applications, like automotive and industrial applications, internet of things applications,medical device, military and aerospace applications, etc. It is required for energy storage, providing energy buffering until other sources of energy are asked for. Tantallum - Polymer Capacitors are also used in computers, mobile phones, laptops, televisions and other digital products.

Working Principle

T540D226M030DT8705 functioning principle is based on both the resource of tantalum and the solid electrolyte that form self-healing mechanism under certain conditions. The solid electrolyte is a stable crystalline state, which formed a polarized layer of film between the anode and the cathode layers. The electric charge could be store in the polarized layer, which governs the capacitor\'s working principle.

Besides the polarized layer of film, a dielectric layer is used between the anode and the cathode too. This dielectric layer composed of various materials, like oxide, nitride or other single- or multi-component compounds. These layers of dielectric and polarized film could store electric energy, and help with determining the capacitance and working voltage of the capacitor.

During the working process of T540D226M030DT8705, when the electric charge flows in the circuit, electrons move from the negative terminal to the positive terminal, thus forming an electric field between the anode and the cathode. This result in a dielectric strength, and electric energy could be stored by the capacitor for later use.
