Tantalum Capacitors

T491A154K035ZT7622 is a type of tantalum capacitor that is used in a wide variety of applications. Tantalum capacitors are characterized by their high reliability, low ESR, and extremely high capacitance to volume ratio. This makes them widely used in a variety of industries, including automotive, aerospace, and industrial electronics.Tantalum capacitors are made using a thin layer of tantalum metal deposited onto an insulated ceramic dielectric substrate. The dielectric is then sealed in a metalized case and connected to the appropriate terminals. This configuration forms a capacitor that has the ability to store energy while also filtering electrical signals. The energy stored in a capacitor is determined by its size, voltage rating, and the type of material used for the dielectric.T491A154K035ZT7622 tantalum capacitors are typically used in high voltage and high current applications, such as DC-DC converters and power supplies. These capacitors are ideal for applications where low ESR and high capacitance are needed along with high precision. The T491A154K035ZT7622 capacitor is rated for up to 130 volts, with a capacitance of 154 kV arbs, an ESR of 0.35 ohms, and a capacitance tolerance of ± 20%.The working principle of a tantalum capacitor is relatively simple. When a positive voltage is applied across the terminals, it creates an electric field that attracts negative charge particles from the surrounding area to the capacitor. This process is referred to as dielectric polarization, which causes an opposite charge to build up at the other terminal. This charge, called a dielectric displacement current, is the energy stored in the capacitor. As the voltage across the capacitor increases, the amount of charge stored increases and the capacitance of the capacitor increases as well.When the voltage is removed, the stored charge is slowly released back into the surrounding area. This process is known as dielectric relaxation and it is why a tantalum capacitor is able to hold its charge for long periods of time. The amount of charge stored in the capacitor is determined by the size of the capacitor, the voltage rating, and the material used for the dielectric.T491A154K035ZT7622 tantalum capacitors are used in a wide variety of applications due to their high capacitance, low ESR, and their ability to hold a charge for long periods of time. These capacitors are ideal for DC-DC converters and power supplies, as well as a variety of other high voltage and high current applications.
