T491A685M010AT capacitors are tantalum capacitors that are highly reliable, long life components often used in a variety of industrial, automotive, and consumer electronics applications. This capacitor has a maximum voltage rating of 10 volts with a temperature coefficient of 5%. It features an Axial-Lead design, Nickel barrier contacts with an Ultrasonic Welded Seal. The single-piece construction construction makes these capacitors highly resistant to corrosion, shock, and vibration, making them an ideal choice for high-reliability applications.T491A685M010AT capacitors are a positive-polarized tantalum type capacitor comprised of two electrodes, a dielectric electrolyte and an anode case. The anode is a molded solid tantalum capacitor with a manganese dioxide electrolyte. The cathode is composed of a nickel-plated steel case and terminal leads extending from each side of the case. When the capacitor is energized a charges builds up on the electrodes and a voltage is produced between them. This voltage is equal to the applied voltage, minus the dielectric absorption effect.The construction of the T491A685M010AT capacitor makes it suitable for a wide range of applications. It can be used in high-reliability automotive and industrial applications due to its extremely low leakage current and high capacitance range. Additionally, the increase in switching power supplies has increased the demand of these types of capacitors. Due to their high capacitance to volume ratio, they are ideal for use in power supply smoothing, filtering and signal smoothing, in applications such as medical equipment, motor drive circuits, laptops, telecom applications and automotive electronics.The working principle of the T491A685M010AT capacitor is based on the use of an electrical charge that is held and stored. The charge is held in an electric field which is created by two metal plates held in an insulating material known as a dielectric. When a voltage is applied to the plates, the electric field strength increases between them, storing energy and providing filtration of an applied signal. This stored energy can then be used to provide a smooth power supply or act as a signal filter.T491A685M010AT capacitors are highly reliable and long-lasting components capable of handling high temperature operating conditions and providing high capacitance for power supply and signal smoothing applications. They are the ideal choice for automotive, industrial and consumer electronics applications, due to their single-piece construction and ability to withstand shock, vibration, and corrosion. In addition, due to their axial-lead design and nickel plated terminals, they provide superior electrical performance and reliability.
