Tantalum Capacitors

Tantalum capacitors are an important component in a range of electronic devices and can be used in a variety of industrial and consumer applications. They are designed to store electrical energy and release it in a controlled manner when needed.Tantalum capacitors have a wide range of benefits, including low equivalent series resistance (ESR) and equivalent series inductance (ESL) values, low dielectric absorption, high thermal stability and high working voltage. They also offer high reliability, long life and resistance to temperature, humidity and vibration.The TR3A475M020C3500 is a type of tantalum capacitor, manufactured by Vishay. It is a high-performance capacitor, designed for use in automotive, aerospace, medical and industrial applications. The capacitor has a low equivalent series resistance (ESR) and equivalent series inductance (ESL) values, and is capable of storing up to 25V of power. The capacitors can operate at a wide range of temperatures, from -55°C to +125°C.

Working Principle

Tantalum capacitors use a tantalum oxide layer as a dielectric material to store electrical energy. When electrical current is applied to the capacitor, a charge builds up on the plates, which are separated by the dielectric material. This creates an electric field between the plates, known as the capacitance. The size of the capacitance is determined by the amount of charge on the plates, the permittivity of the dielectric material, and the area and spacing of the plates.The TR3A475M020C3500 capacitor has a capacitance of 47µF and is capable of storing up to 25V of power. It has a low equivalent series resistance (ESR) and equivalent series inductance (ESL) values, making it suitable for many applications where high performance and reliability is required.When electrical current is applied to the capacitor, the charge stored on the plates will start to discharge. The rate at which this occurs depends on the size of the capacitor and the amount of current flowing through it. Once the charge has been depleted, the capacitor will no longer be able to store electrical energy.

Application Field

Tantalum capacitors are commonly used in a range of different applications and industries, including automotive, aerospace, medical and industrial. The TR3A475M020C3500 capacitor is designed for use in high performance applications, where a combination of high performance, high reliability and low resistance is required.For automotive applications, the capacitor can be used in power supplies, motor power supplies, and power conditioning and control. It is also suitable for use in aerospace applications, such as avionics and flight control systems, as well as in medical devices and other industrial applications.Due to its high reliability and low equivalent series resistance (ESR) and equivalent series inductance (ESL) values, the TR3A475M020C3500 capacitor is capable of providing an excellent level of performance in a range of demanding applications.
