Tantalum capacitors are used in many applications for their convenience and small size. TPSB335M020R1300 is a surface mount tantalum capacitor of high voltage and low ESR, it is very popular in power supply circuits, microprocessors, motherboards and other electronics that require filtering or buffering of a low-impedance lead.

This capacitor has electrical properties that are typical of tantalum types: very low ESR, moderate capacitance, high operating voltage and high ripple current ratings. The robust construction makes it a good choice for applications requiring accurate voltage regulation, ripple suppression and filtering of high-frequency noise.

In terms of application fields, TPSB335M020R1300 capacitors are mostly used in power supply filtering, decoupling and bypassing circuits, often in combination with other components. They are also well suited for low-noise AC/DC converters, DC/DC converters, microprocessors, automotive applications, DSPs and mobile communication systems.

The working principle of everyday capacitors is based on the law of capacitance, which states that when a voltage is applied to two parallel electrodes, an electric field is generated that causes electrons to accumulate on one electrode, creating an electric charge. This charge creates a counter electric field in opposite direction of the first one, which opposes the buildup of further electrons and cancels the applied voltage.

In the case of tantalum capacitors, when voltage is applied, electrons accumulate on the tantalum anode forming an electric field. When the voltage reaches a certain level, the electrons repel each other and a dielectric layer is formed between the anode and the cathode. This layer is referred to as the tantalum pentoxide (Ta2O5) and it acts as an insulator and effectively separates the two electrodes.

When the voltage drops down, the dielectric layer dissipates, allowing current to flow from one electrode to the other. This is why capacitors are often used to filter or buffer low-impedance leads. TPSB335M020R1300 capacitor, due to its robust construction, allows for accurate voltage regulation and ripple suppression.

To sum up, TPSB335M020R1300 is a high-voltage, low-ESR, surface-mount tantalum capacitor, mainly used in power supply filtering, decoupling and bypassing circuits, as well as low-noise AC/DC and DC/DC converters, automotive applications and mobile communication systems. Its working principle is based on the law of capacitance, with a dielectric layer formed by depletion of electrons on the tantalum anode.
