Tantalum Capacitors: M39003/09-0252H Application Field and Working PrincipleTantalum capacitors are components for electronic equipment with classification drawn from two of their most important attributes: case type and configuration. In the classification of case type, the M39003/09-0252H is an example of a molded tantalum capacitor, which is a type of surface mount capacitor. When selecting a capacitor for application, the most important considerations are capacitance, voltage, access to service data, construction type, temperature range, and dimensions.Molded Tantalum CapacitorsMolded tantalum capacitors refer to components that are manufactured by placing tantalum powder in a mold. The powder is then compressed and a conductor is inserted, creating a monolithic component. This type of capacitor offers superior performance as compared to clip-in and radial types. Apart from their higher performance, molded type capacitors also occupy less real estate on a board, making them ideal for space-constrained applications. The significant advantage of this type of rugged construction is its low susceptibility to mechanical damage.M39003/09-0252H CapacitorThe M39003/09-0252H is a molded tantalum surface mount capacitor suitable for military, medical, and aerospace applications. This device is manufactured as an axial-lead capacitor with a flat-top terminal that comes in seven sizes ranging from 0.35mm to 1.65mm in diameter.The M39003/09-0252H has a low profile of 0.85mm and a wide range of operating temperatures of -55°C to +125°C. Its operating voltage is 22V and a maximum capacitance of 10,000 pF (10μF). It also features and overall height of 1.2mm when the terminal cap is mounted.Working PrincipleTantalum capacitors are generally constructed with two capacitance phases, one for each side of its capacitor plates. In the M39003/09-0252H, the metallic plates are formed in the shape of a cylindrical disc that is then encased inside a non-conductive material.The capacitor works on the principle of switching the negative and positive voltage to create a flow of electrons. This flow brings an electrical charge that is stored within the plates and lining between the plates. As the voltage increases, the capacitance also increases.However, as the amount of charge accumulates the plates become increasingly charged, thus decreasing the capacitance. This continuous cycle of charge creates a sort of electrical oscillation or waveform, which can be used for various signal processing tasks and applications.ConclusionThe M39003/09-0252H is an example of a molded tantalum capacitor, which offers superior performance and occupies less real estate than other types of capacitors. Its operating temperature range of -55°C to +125°C is wide enough to be used in many types of applications. Additionally, its maximum capacitance of 10,000 pF and its operating voltage of 22V makes it an ideal choice for many military, medical, and aerospace applications requiring a reliable power source. Tantalum capacitors work on the principle of switching negative and positive voltages to generate a flow of electrons. This flow creates a cycle of charge and discharge that results in an electrical oscillation, which can be used for various applications. The M39003/09-0252H is an ideal capacitor for applications requiring a reliable power source and superior performance.
