T491A104K050AN Tantalum Capacitors: Application Field and Working Principle

Tantalum capacitors, also known as tantalum electrolytic capacitors, are distinct from other types of capacitors due to their use of tantalum metal as an electrode and dielectric, as well as their high capacitance per unit volume. These capacitors are widely used in applications such as memory modules, desktop PCs, portable devices, digital cameras, car electronics, and more.

T491A104K050AN tantalum capacitors are surface mount devices that feature a chip design. This low-profile capacitor, with a total height of just 1.2mm, offers a high capacitance, low ESR, and excellent performance in a wide range of applications, such as power supplies, communication systems, A/V and personal electronics. It is also resistant to moisture and temperature and can handle high vibration levels.

T491A104K050AN capacitors offer a variety of features, including self-healing (SH) technology and low impedance. SH technology eliminates the need for power cycling when a failure occurs and eliminates over-pressure and heat accumulation. The low impedance helps ensure that the capacitor can provide power to the system even in conditions of high frequency noise.

T491A104K050AN tantalum capacitors come in a range of shapes and sizes, with a wide range of capacitance values to meet specific system needs. Common sizes include 0603, 0805, and 1206, and capacitances range from 1uF-2.2uF. The capacitors are also polarized and equipped with a positive anode and negative cathode.

The working principle of tantalum capacitors is simple. When a voltage is applied to the terminals, the positive side of the capacitor (the anode) attracts free electrons, while the negative side (the cathode) releases electrons. This in turn creates a reverse electric field, which stores the energy as electrostatic energy. The tantalum capacitors are able to store a very large amount of energy in the form of an electric field, making them ideal for applications that require a large amount of power.

T491A104K050AN tantalum capacitors offer a range of benefits, from their resistance to high vibration levels to their low ESR and high capacitance. In addition, they are widely used in a range of applications, including memory modules, desktop PCs, portable devices, digital cameras, and car electronics. With their high capacitance, long life expectancy, and robust design, these tantalum capacitors are ideal for power supply and communications requirements.
