TH3B475M020F1900

Tantalum capacitors are among the most commonly used in electronics. They play an important role in providing components with the electrical energy they need to function properly. TH3B475M020F1900 is a type of tantalum capacitor. It is a tantalum electrolytic capacitor with an anode made of tantalum and a cathode of manganese dioxide that acts as the electrolyte. This type of capacitor is available in a variety of sizes, from 0.15uF to 470uF, and with a rated operating temperature range from -55°C to 85°C.

The TH3B475M020F1900 is primarily used in power supplies, for its ability to store charge for a longer period of time than other types of capacitors. Its high capacitance makes it ideal for use in applications that require long periods of charge storage. Another important application area of the TH3B475M020F1900 is in protecting electronic components from high power surges. The capacitor stores a large amount of charge, which in turn can absorb any large voltage surges and thus protect components.

The working principle of a tantalum capacitor is based on the principle of electrostatic attraction. Two electrically conductive plates, one positive and one negative, are suspended in a non-conductive material. When a voltage is applied across the plates, positive charges accumulate on one plate and negative charges on the other. As the plates become more and more charged, the amount of charge accumulated begins to create a barrier between the two plates, causing a potential difference. This potential difference is the capacitance, and the rate at which charge accumulates is the capacitance.

Tantalum capacitors are also known for their high reliability, due to their robust construction and precise fabrication and materials. The high operational temperature range makes them suitable for many demanding applications. The TH3B475M020F1900 also features good inductance, which helps reduce the amount of ringing caused by high frequency signals.

Apart from their primary use in power supply applications and surge protection, tantalum capacitors can also be used in signal filtering. The high capacitance makes them perfect for eliminating high and low frequency interference, as well as filtering out pulse noise. They are also used in analog circuitry, for decoupling, noise reduction and high frequency ac signals.

In conclusion, the TH3B475M020F1900 is a reliable and versatile tantalum capacitor with a variety of applications in power supplies, signal filtering and surge protection. Its high capacitance and robust construction makes it ideal for many demanding applications.
