T58W0476M8R2C0500

Tantalum-polymer capacitors are one of the more unusual types of capacitors available today. Unlike traditional aluminum electrolytic capacitors, which have a solid-state electrolyte, these devices feature a thin polymer layer between two plates of the tantalum material. This layer acts as an electrolyte, allowing the tantalum plates to charge and discharge without the need for traditional electrolyte.

The T58W0476M8R2C0500 is a surface-mount tantalum-polymer capacitor. It\'s designed to act as a multi-layer chip capacitor with a high capacitance value of 0.0082µF in 2.5mm×3.3mm form factor. It operates in a temperature range of -55°C to +85°C, and offers a capacitance tolerance of ±20%.

The T58W0476M8R2C0500 capacitor has a wide range of applications. First, it works well in low-voltage applications, such as computer motherboards and other electronics components that require high capacitance values. It also has a low ESR compared to traditional aluminum electrolytic capacitors, which makes it ideal for high-frequency switching applications, like switching power supplies. Additionally, it offers excellent reliability and temperature stability, making it particularly well suited for automotive applications.

The working principle of a tantalum-polymer capacitor is similar to that of other capacitor types. Its two plates of tantalum material act as conductors, and the thin layer of polymer between them acts as an electrolyte. When an electric field is applied to the capacitor, charge is stored on both plates. The amount of charge stored on each plate depends on the applied voltage and the capacitance of the device. Eventually, the charge on the capacitor plates reaches a state of equilibrium, where the current flowing across the capacitor is equal to the amount of charge stored on each plate.

In summary, the T58W0476M8R2C0500 is a surface-mount tantalum-polymer capacitor that offers a high capacitance value of 0.0082µF in a 2.5mm×3.3mm form factor. It has a wide range of applications, including low-voltage and high-frequency switching applications, as well as automotive applications. Its working principle is similar to that of other capacitor types, with two plates of tantalum material acting as conductors, and a thin layer of polymer acting as an electrolyte.
