Tantalum Capacitors: TPSC686K006R0200 Application Field and Working Principle

Tantalum capacitors are electrolytic capacitors that are widely used in various electronic equipment, such as computer motherboards, TV sets, etc. They are often an integral part of the design for power supply circuits requiring high capacity and low cost.The TPSC686K006R0200 is an example of a tantalum capacitor. It is an axial, organic, radial-leaded, cathode-marked, surface-mount chip capacitor. With a capacitance of 6.8µF, a voltage rating of 6.3V, and a tolerance of ±20%, this capacitor is suitable for low-voltage applications. It is also resistant to moisture and has excellent stability when it comes to temperature fluctuations, making it ideal for use in a range of environmental conditions.The working principle of a capacitor is based on the ability of two metal plates separated by an insulator (dielectric) to store an electric charge. For a tantalum capacitor, the two plates are formed of the metal, tantalum, and their separation is achieved by a dielectric of tantalum pentoxide, or Ta2O5. When a DC voltage is applied to the capacitor, the pieces of metallic tantalum are instantly polarized, and the dielectric material will begin to capacitate the circuit with the desired capacitance. The charge stored by a tantalum capacitor is directly dependant on the plate area, plate separation and the dielectric constant of the material between them. Since ta2O5 has a high dielectric constant compared to other dielectric materials, it allows tantalum capacitors to have a smaller size, but still offering a large capacitance. As the internal resistance of a tantalum capacitor is very low, it is capable of having a very thin oxide layer, which provides a high temperature stability and reliability for the capacitor\'s lifetime. Additionally, due to tantalum’s natural ability to absorb moisture it has a built-in self-healing property, which enables any electrolytic leakage to be automatically sealed in case of any short circuit caused by a foreign particle or corrosion.Tantalum capacitors are well-suited for many different applications because of their low profile, low ESR (Equivalent Series Resistance), and long-term reliability under extreme temperatures. One of the main applications of TPSC686K006R0200 is in the switching power supplies. Numerous prototype circuit designs that use high-power, high-frequency switching regulators, require the use of an output filter capacitor to reduce the ripple current. The TPSC686K006R0200 works as anOutput Storage Capacitor (OSC) and it is designed to provide decoupling, voltage damping and input filtering, enabling the regulator to operate efficiently and accurately.In medium-power circuits, TPSC686K006R0200 can also be found in buck boost converters. Buck boost converters are used for low-voltage power delivery for applications such as digital displays, LED light strings and small motors, where the input voltage may be different from the anticipated load voltage. The TPSC686K006R0200 helps to maintain a steady output voltage as the input voltage varies.TPSC686K006R0200 can also be found in charging systems. Here, it is typically used as a filter capacitor to help to smooth out charging current and maintain an even voltage for cellphones and other battery powered devices.Lastly, it is worth noting that TPSC686K006R0200 is a high-performance capacitor and is suitable for use in applications that require high capacitance and high stability in a very confined space. This makes it resistant to temperature, humidity, radiation and other external influences, allowing it to be used in medical and military equipment.In conclusion, TPSC686K006R0200 is a widely used tantalum capacitor that is especially suitable for applications requiring low voltage and high capacitance. Its features and high performance make it a worthwhile choice of capacitor regardless of the application.
