Tantalum Capacitors

Tantalum capacitors are small electronic components composed of tantalum and a mixture of oxide and manganese dioxide that are used to store electrical energy. They offer superior performance over other types of capacitors, such as ceramic or electrolytic, in many different applications.

The T495B475K025ATE900 is an example of a tantalum capacitor. It is a polymer (solid-film) device that offers high capacitance values and low ESR (equivalent series resistance) ratings. These factors make it ideal for many different applications, such as bypass and coupling applications in power electronic designs, audio circuits, and high-frequency switching. It can also be used in applications requiring low-noise operation and good steady-state/long-term performance.

Application Field and Working Principle

Tantalum capacitors have a wide range of applications, from high-voltage power transmission and distribution to low-voltage signal filtering. In many applications, such as automotive, RF, and power supplies, these components are used for stabilizing output voltages and reducing electrical noise. They are also used in low-frequency AC/DC applications, such as motor control and lighting, to reduce the amount of energy required to power the device.

Tantalum capacitors are unique because they are highly responsive to fast changes in voltage or current. A capacitor works by accumulating electric charge when a voltage is applied across its terminals. This charge is stored and discharged when the appliances connected to it absorbs or draws power. The T495B475K025ATE900 is specifically designed to be highly reactive, with a very low ESR rating, and wide capacitance range.

The capacitance of a capacitor is dependent on the type of material used, the size of the capacitor, and the applied voltage. At low temperatures and low voltages, the capacitance of the T495B475K025ATE900 is still quite high, making it an excellent choice for low-noise operation. Its low ESR rating also makes it an excellent choice for applications that require high current handling.

One other important factor to consider is the life expectancy of the device. The T495B475K025ATE900 has a rated life of 2000 hours, making it suitable for many demanding applications that require long-term reliability. It also includes a temperature derating curve that allows the user to accurately calculate the expected life based on the ambient temperature and operating conditions.

Tantalum capacitors are a great choice for many different applications, thanks to their high capacitance values, low ESR ratings, and long life expectancy. The T495B475K025ATE900 is a great example of these components, and can be used in a wide range of applications that require reliable performance and low noise operation.
