Working Principle of T540D476K020BH8505

T540D476K020BH8505 is a polymer tantalum capacitor, which consists of two conductive plates separated by an anodic insulating material. These plates are insulated by the electrolyte, which is usually an organic solvent containing a high concentration of the electrolyte salt. This is why they are also referred to as ‘wet’ capacitors. The electrolyte salt allows the capacitor to store energy in the form of a charge. The electrons move freely between the plates, creating a current when a voltage is applied across the plates.

The charge stored on the capacitor is held in place by the effect of the static field created when the negative and positive charges on each plate are attracted to the opposite charge. The capacitor\'s capacitance depends on several factors, including the size of the plates, the distance between them, and the material of the conductive plate. The capacitance of wet tantalum capacitors is usually higher than that of dry tantalum capacitors.

T540D476K020BH8505 is designed for use in high-temperature applications. It has a maximum operating temperature of 125°C and offers stability and reliability at high temperatures. It is also resistant to humidity and has a shock resistance of 8G. The capacitor is designed to offer excellent capacitance-temperature characteristics, making it suitable for a wide range of applications.
