Tantalum - Polymer Capacitors

Tantalum polymer capacitors are a type of electrolytic capacitor. They are widely used in electronics ranging from consumer electronics, portable equipment, and automotive uses. They are manufactured mainly from tantalum and a conductive polymer.The M551B347K030AG is a type of tantalum-polymer capacitor. This capacitor has a capacitance of 346µF, operates at a voltage of 10V and has a low profile of 5.0mm x 7.3mm. Its temperature characteristics range from -30°C to 85°C. This capacitor is ideal for applications like power supplies, handheld electronics, and automotive applications.Tantalum-polymer capacitors consist of three main parts: a dielectric, a conductive polymer, and a conductive metal electrode. The dielectric is a layer of tantalum pentoxide. This layer has an overall high dielectric constant, which allows for a high capacitance to be achieved in small physical sizes. The conductive polymer provides an electrical connection to the dielectric layer and acts as an electrolyte for the electrolytic capacitor. The metal electrode forms the outermost layer of the capacitor and provides the connection to the circuit.The working principle of a tantalum-polymer capacitor is similar to that of an electrolytic capacitor. When a voltage is applied to the capacitor, the dielectric layer absorbs the energy and stores it as an electric field in between the electrode layers. As current flows through the capacitor, the electric field is altered and an electrical charge is stored between the layers. When the voltage is removed, the electric field dissipates, and the capacitor’s charge is also released. This process allows the capacitor to function as aCapacitance Voltage (CV) device storing and releasing energy.The M551B347K030AG is mainly used in high-reliability applications due to its excellent characteristics. Its low profile and tight footprint allow for it to be used in confined spaces. Its temperature characteristics also allow it to be used in harsh and harsh environments. Its high capacitance-voltage ratio makes it ideal for energy storage applications such as UPS systems and DC-DC converters. The capacitor also has excellent ripple-current capability, allowing for a smooth supply of energy over a range of frequencies.Overall, the M551B347K030AG is an excellent choice for a variety of applications where high-reliability and low profile are desired. Its low leakage and excellent temperature characteristics make it an ideal choice for a variety of electronic applications. Its high capacitance-voltage ratio and excellent ripple-current capabilities make it a suitable choice for energy storage applications.
