Tantalum - Polymer Capacitors

Tantalum-Polymer capacitors are a type of capacitor constructed with a thin layer of dielectric polymer sandwiched between a pair of metal electrodes. The electrodes are made of rolled tantalum foil and are separated by a thin film of polymer dielectric material. The use of tantalum-polymer capacitors is increasing, particularly in the aerospace, military, industrial and medical fields.The main advantages of a tantalum-polymer capacitor over other types of capacitors are its small size and low equivalent series resistance (ESR). This makes them ideal for high-frequency and high-power applications. Additionally, the unique metal-polymer construction gives them superior performance to ordinary aluminum and electrolytic capacitors. They are also known for their high capacitance density, allowing for smaller sizes than comparable capacitors.Tantalum-Polymer capacitors are typically available in monolithic, radial, and axial form. The monolithic type is constructed as a single unit and is typically used in portable electronic devices such as cell phones and digital cameras. The radial type is constructed with a metal can to encase the components and is mainly used in industrial, medical and military applications. The axial type is mounted on circuit boards and is usually used in audio, RF, and cellular communications applications.The T520V337M004ATE007 is a surface-mount tantalum-polymer capacitor. It is a wrap-type capacitor with a small footprint and low ESR. It is rated for a voltage of 6.3 volts and a temperature range from -55°C to +85°C. This capacitor is suitable for use in automotive, avionics, and military systems requiring a reliable capacitor with low impedance, as well as in consumer applications such as digital cameras and cell phones.The working principle of tantalum-polymer capacitors is based on electrostatic storage of energy. When a voltage is applied to the capacitor\'s electrodes, an electric field is created in the dielectric material between the electrodes. This electric field causes an electric charge to be stored on the conductive surfaces of the electrodes. This electric charge creates an electrostatic field in the dielectric material, which is linked to the electric field, causing it to store energy. When the electric field is reversed, the energy stored in the capacitor is slowly released.Tantalum-polymer capacitors offer superior performance compared to other types of capacitors due to their higher capacitance density, lower equivalent series resistance (ESR), and higher dielectric constant. This makes them well-suited for high-power and high-frequency applications. Additionally, their robust construction and small size mean they are suitable for a wide range of applications, from consumer electronics to aerospace, military, and medical equipment.
