Tantalum CapacitorsTantalum capacitors are one of the most reliable and commonly used capacitive components. The M39003/03-0175/TR, one of the many tantalum capacitors available today, is no exception—boasting reliability, high capacitance, and stability under a variety of conditions. This article will briefly describe the application field and working principle of this and other tantalum capacitors.Tantalum capacitors are used in a variety of electronic applications and are a popular choice for many applications, ranging from consumer electronics to more demanding industrial applications. Primarily, tantalum capacitors are used to provide energy storage, filtering, and decoupling. In particular, they are favored for their small size, high capacitance, and excellent stability when exposed to varying temperatures.The M39003/03-0175/TR is a surface-mount, tantalum capacitor. It has a the standard *EIA class 1 construction and its capacitance rating ranges from 0.047µF to 2.2µF. Its capacitance tolerance is between ±20% and ±10%. The capacitor is rated for voltage between 4V and 25V, and operates in temperatures ranging from -55°C to 85°C. Due to its robust construction, the M39003/03-0175/TR is well-suited for reflow soldering and semi-auto soldering.At a fundamental level, a tantalum capacitor works the same way as all other types of capacitors—it stores energy in the form of an electric field between two conductive plates. The materials used and the construction of the capacitor affect its performance.In a tantalum capacitor, the plates are made of either tantalum powder or tantalum oxide. The other components consist of thin layers of an insulator, such as aluminum oxide. The ceramic plate is the dielectric, or nonconductive material, between the plates and provides the basis for charge-discharge operations.The important characteristics of a tantalum capacitor are its capacitance, voltage rating, dissipation factor, and ESR. Capacitance is measured in farads, and its efficiency can be improved by increasing the surface area of the plates. Voltage rating, measured in volts, refers to the maximum voltage the capacitor can handle before breaking down or failing. The dissipation factor and ESR, measured in Ω and mΩ, respectively, indicate how efficient the capacitor is at storing and releasing electrical energy.The construction of a tantalum capacitor also influences its functionality. A standard tantalum capacitor consists of tantalum caps, anode end caps, and a negative end cap. The anode end is a thin layer of materials that keeps the electric current from flowing between the anode and the cathode. The negative end cap acts as the contact point for the positive terminal of the capacitor, preventing the capacitor from discharging. The tantulum caps are the primary sources of the capacitor’s capacitance.In conclusion, the M39003/03-0175/TR is a reliable, high-capacitance surface-mount capcitor that operates in temperatures ranging from -55°C to 85°C. This tantalum capacitor offers numerous advantages over other types of capacitors, including superior stability, reliability, and high capacitance ratings. Furthermore, its efficient construction provides excellent performance in a variety of applications, from consumer electronics to more demanding industrial applications.
