Tantalum-Polymer Capacitors have proven to be an invaluable tool in the electronics industry. These capacitors combine the features of a tantalum capacitor with a polymer substrate to create a high-performance, high-reliability solution for many applications. The T550B476K050AH4251 is one of these capacitors, designed for use in a wide array of applications and environments. This article will explore the application fields and working principles of this capacitor.

Applications

The T550B476K050AH4251 Tantalum-Polymer Capacitor is ideally suited for applications such as power input/output (I/O) decoupling and filtering, voltage regulation, energy storage, controlling low-frequency oscillations and as a filter. The capacitor has a higher capacity than other types of capacitors, and can store more energy. It is frequently used in high-frequency applications, such as mobile phones, digital cameras and other devices. Furthermore, the capacitor is designed for high-reliability and extreme-temperature applications.

The capacitor has a wide operating temperature range, from -55°C to +125°C (-67°F to +257°F), meaning that it can be used in a variety of different temperature environments. Additionally, the capacitor is low-impedance, meaning that its effective series impedance (ESR) and equivalent series inductance (ESL) are very low. This makes the capacitor ideal for high-frequency/low-noise applications. The capacitor can handle up to a maximum capacitor voltage of 6.3VDC (direct current) and a nominal capacitance of 4.76uF (micro-Farads).

Working Principles

The T550B476K050AH4251 Tantalum-Polymer Capacitor features an anode which is made from aluminium and is metallized for increased reliability. This is then combined with a solid tantalum electrolyte, which is mixed with hydrogen ions, creating an ionically conductive solid electrolyte. The electrolyte is then placed on a dielectric of polymer material, which acts as an insulator and provides the necessary electric separation. The combination of these materials forms the basis for the capacitor’s operation.

When a voltage is applied across the capacitor, a charge is stored in the capacitor\'s dielectric, thus creating an electric field across the capacitor. This electric field results in a voltage drop across the capacitor, and an electric current flows between the anode and the cathode. The current flow causes the hydrogen ions to migrate through the electrolyte, and the electric field applies a force, which causes the charge to be stored in the dielectric, thus creating capacitance. The capacitor\'s capacitance will remain steady, until the electric field is removed, and charge is no longer stored in the dielectric.

The attractive feature of the T550B476K050AH4251 Tantalum-Polymer Capacitor is its combination of high-reliability and low-impedance. This makes it well suited for use in applications which require the highest levels of performance and reliability. The low-impedance also makes it useful for high frequency applications, as it reduces noise, and reduces the risk of electronic interference. Additionally, the capacitor is designed for use in extreme temperature environments, meaning that it can be used in a variety of different applications.
