Tantalum Capacitors – 299D476X0020EB1 Application Field and Working Principle

Tantalum capacitors are an essential component of a wide variety of electrical and electronic systems. They have a long history and are still used in a multitude of modern applications. In this article, we explore the 299D476X0020EB1 series of tantalum capacitors, their application field, and the principle on which they operate.The 299D476X0020EB1 series of capacitors is a high-frequency, surface-mount capacitors with two terminals. It is manufactured using a non-conductive polymer film dielectric which is then coated in tantalum metal to form a highly reliable, low-leakage device. The capacitor’s operating temperature is between -55°C and +125°C, the dissipation factor is no more than 0.4%, and the capacitance range is between 22 pF to 2000 pF. It also has a working voltage of up to 50V which further adds to its reliability.Due to their small size, low cost, and high reliability, tantalum capacitors are widely used in a variety of electronic systems including telecommunications, automotive, consumer electronics, medical, and space systems, among others. One of their main applications is in military systems where they need to be able to withstand in extreme temperatures and environments.Tantalum capacitors work by and are based on the same principle as other kinds of capacitors. They store energy in an electrical field between two surfaces, usually two metal plates and a dielectric material. When a voltage is applied across the plates, it produces an electric field which stores energy in the form of an electrostatic charge made up of opposite charges. Tantalum capacitors are different from other electrolytic capacitors because their resistivity decreases as the temperature increases, making them less affected by temperature change and suitable for high frequency applications.In summary, the 299D476X0020EB1 series of tantalum capacitors is a highly reliable, low-leakageand and resectable capacitor with a high operating temperature,high working voltage, and varying capacitance range. It is used in a variety of electronic and electrical systems for its small size, low cost, and reliability. Its operation is based on the same principle as other kinds of capacitors, but its resistivity increases with temperature which makes it suitable for high frequency applications.
