Introduction to Tantalum Capacitors

Tantalum capacitors are a type of electrochemical capacitor that offer high performance and reliability compared to other types of capacitors. This property makes them ideal for a wide range of applications, ranging from general-purpose and low-cost capacitors, to specialized high-performance applications.Tantalum capacitors are constructed using a combination of tantalum rods and foil that are surrounded by an electrolyte solution. This provides a relatively high conductivity and enables the capacitor to store a large amount of electrical energy in a small package. The size and shape of the capacitor can vary, depending on the type of application.The most common type of tantalum capacitor is the T86E476K020EBAL application. This type of capacitor is designed for high quality audio applications, such as CD players and pre-amps. It has a rated capacitance of 0.22F and an equivalent series resistance (ESR) of 20mΩ. The capacitor is also rated for a voltage of up to 50V and can withstand a wide temperature range of up to 105°C.

Working Principle of T86E476K020EBAL

The working principle of the T86E476K020EBAL is based on the principle of electrochemical double layer capacitance (EDLC). This type of capacitor involves the formation of a thin film of electrolyte between two conductive plates. When a voltage is applied across the plates, the electrolyte absorbs electrons from one of the plates and releases them to the other plate. This creates an electrostatic charge thus forming a stable capacitance.The amount of charge stored in the capacitor is determined by the size and shape of the electrolyte gap, as well as the capacitance of the electrolyte itself. The larger the gap and capacitance, the higher the amount of charge that can be stored. The ESR of the capacitor is also important as it determines the amount of resistance that exists in the capacitor when a voltage is applied across it. The T86E476K020EBAL is designed to offer a high capacitance in a small package, while maintaining a low ESR. This makes it highly suitable for audio applications, where it can provide a reliable and stable audio signal.
