Tantalum capacitors belong to the class of electrolytic capacitors and are generally polarized capacitors. Hydrolysis of a solution of a tantalum salt (tantalum pentoxide, Ta2O5) forms the dielectric layer on the surface of the tantalum weave, which is then soaked and impregnated. The most commonly used type of tantalum capacitor is a sintered tantalum capacitor (SMC) with a tantalum anode and a liquid manganese dioxide cathode. This type of capacitor, designated as T540B107K004AH85107610, is a non-solid polymer-based tantalum capacitor, and the cathode utilizes an organic conductive gel to allow lower voltage, higher capacitance and higher working ripple performance.

The main application of T540B107K004AH85107610, as with most other tantalum capacitors, is as decoupling, filtering and bypass capacitors in high-frequency switching regulators and power supplies. It is also used as a timing capacitor in oscillator circuits, and it can also be used as a back-up power supply capacitor during power failures or brown-outs. Additionally, the T540B107K004AH85107610 capacitor is also used in switching circuits, and it can be used in a variety of audio and low power equipment, including amplifiers and sound processing, and mobile phone circuits.

Working Principle. The capacitance of the T540B107K004AH85107610 capacitor is determined by two factors, the size and permittivity of the dielectric layer. In contrast to solid tantalum capacitors, in non-solid polymer-based tantalum capacitors the ratio of dielectric layer size to cathode volume (capacitance factor) is typically much higher, generating higher capacitance for better performance in compact designs. This is achieved by saturating the dielectric layer with a variety of polymer compounds, which are compressible and provide very uniform distribution of ions. The T540B107K004AH85107610 component also uses an electrolyte, which is a conductive material that helps react with the electrolyte on the inside of the capacitor, producing an energy storage field that is a function of the distance between anode and cathode. This energy storage field is further improved by the high capacitance factor, potassium storage capacity, and low ESR and ESL of the dielectric layer.

In conclusion, the T540B107K004AH85107610 component belongs to the category of Tantalum - Polymer Capacitors and is mainly used in decoupling, filtering and bypass applications for high-frequency switching regulators and power supplies. It is also used in oscillator circuitry, low power equipment, and back-up capacitors in case of power failures. The capacitance of the component is derived from the two factors of size and permittivity, and the benefits of the component such as low ESR and ESL of the dielectric layer, high capacitance with a compact design, and the electrolyte-cathode reactions are the key factors contributing to its performance.
