Tantalum capacitors are a type of electrolytic capacitor that are commonly used in electronic circuits. They are often used in circuits designed for high-frequency or high-voltage applications. The TR3A475M020C1800 is a such tantalum capacitor that has been designed specifically for these applications. This article will provide an overview of the application field and working principle of this particular capacitor.

Application Field

The TR3A475M020C1800 is a general-purpose tantalum capacitor with a high voltage rating of 20V and a capacitance of 475uF. It is primarily used in high-frequency, high-voltage applications such as instrumentation, radio receivers, and noise filters. This capacitor is also suitable for power supply applications, such as rectifier circuits, DC/DC converters, and lighting units. The TR3A475M020C1800 has a wide capacitance range, with a range of 4µF to 470µF available. It is also available in two sizes, 210mil or 350mil, to fit different application requirements.

Working Principle

The TR3A475M020C1800 uses a tantalum pentoxide electrode instead of the common aluminum or tantalum oxide layer. This material has high dielectric strength and offers excellent capacitance and extremely low ESR (equivalent series resistance). This makes it ideal for high-frequency and high-voltage applications. The working principle of the TR3A475M020C1800 is that when it is connected to a power source, the current will flow through the tantalum pentoxide and the electrolyte, creating an electric field. This electric field will cause the charges to be attracted to the dielectric material and accumulate, forming an electrical capacitance. Thus, the capacitor can store electrical energy and discharge it when needed.

The TR3A475M020C1800 tantalum capacitor is a general-purpose capacitor specifically designed for high-voltage and high-frequency applications. Its wide capacitance range and excellent ESR makes it suitable for noise suppression and power supply applications. It is also available in two sizes to suit different requirements. The working principle of the TR3A475M020C1800 is based on the accumulation of charges on the dielectric tantalum pentoxide, creating an electrical capacitance that can be used to store energy and then discharge when needed.
