Application Field

T491C686M010AT4280 are mainly used in several applications, including portable communications equipment, computers, automotive electronics, and consumer-electronics products. Because of their self-healing feature, they can be used for applications with very high levels of vibration. They are ideal for power supplies and in noise-filtering applications.

T491C686M010AT4280 capacitors are also suited for rail and vehicular applications, such as in brake control units, electronic fuel pumps, HVAC systems and power drive systems. They also find ready use in dc-to-dc converters and electro-mechanical energy conversion.

Working Principle

T491C686M010AT4280 capacitors are based on the principle of electrochemical capacitance. This principle states that the capacitance of a capacitor is directly proportional to the surface area of the electrodes and inversely proportional to the distance between them. Electrochemical capacitance occurs when an electrolyte is placed between two electrodes made of a porous metal. The electrolyte provides a path for ions and electric charge to flow in order to maintain the voltage across the electrodes. When a voltage is applied to the terminals of a capacitor, the electrolyte\'s ions travel through the porous metal electrodes, creating an electric field in the space between them. The electric field stores the energy, thus forming a capacitance.

T491C686M010AT4280 capacitors are extremely reliable because their working principles take into account the fact that their materials will degrade over time due to oxidation and moisture. The electrodes themselves are coated in an insulator that prevents oxidation and maintains their integrity for longer. The capacitors also have a self-healing feature that allows them to automatically repair themselves, ensuring that their performance remains optimal.

T491C686M010AT4280 are extremely useful due to their characteristics and performance. They offer a combination of high reliability, long life, high volumetric efficiency and low cost that makes them ideal for a variety of applications. They are often used in especially demanding conditions and environments, making them reliable and trustworthy components.
