Tantalum Capacitors

152D686X0020R2B Application Field and Working Principle

Tantalum capacitors are a type of capacitor used in different electronic devices, such as digital cameras, mobile phones, PDA\'s and audio devices. These capacitors are characterized by their large capacitance-to-volume ratio, high stability, low leakage current, and low ESR (equivalent series resistance). They are also known for their relatively low price and wide availability. The 152D686X0020R2B is a popular type of tantalum capacitor.The 152D686X0020R2B is a surface-mount, axial leaded, tantalum capacitor. It has a maximum working voltage of 6.3V DC, a rated capacitance of 680μF and a tolerance range of -20% to +50%. This makes it suitable for a variety of applications, such as high frequency filters, audio applications, power supplies, and high voltage smoothing. Its maximum operating temperature varies from -55°C to 85°C, and its total dissipated energy is 0.19 J.The 152D686X0020R2B operates on the principle of electrostatic capacitance. This means that it stores electrical energy in the form of an electrical field between two electrically conductive plates. The two plates are usually made up of a tantalum-oxide-suppressor-dielectric layer and a conductive coating known as an anode. The capacitance of the device is determined by the amount of electrical charge that can be stored in the plates.The capacitance and other electrical properties, such as leakage current and ESR, can be improved by the addition of a further layer of dielectric material to the structure. In the case of the 152D686X0020R2B, a polymeric layer of dielectric material is used, which helps to reduce its leakage current and improve ESR.The 152D686X0020R2B is popular due to its small size, so it can be used in cramped spaces, and due to its good temperature characteristics, which makes it tolerant to variations in temperature. It is also quite robust, and has a high voltage tolerance.Overall, the 152D686X0020R2B is a versatile device, suitable for a wide range of applications, and is an ideal choice for those who need a capacitor with a low leakage current, good temperature characteristics, and a high rated capacitance. Its low cost and wide availability make it a popular choice for designers.
