Tantalum capacitors are, along with ceramic capacitors, one of the primary categories of capacitors. Capacitors are electronic components used for the storage of energy in an electrical field. The M39003/01-8191H is a type of solid tantalum capacitor, chosen for its high volumetric efficiency, low ESR, and low leakage characteristics. It is used in electronic systems in fields such as automotive, portable, and consumer electronics.The general working principle of tantalum capacitors is the same as other types of capacitors. In a solid tantalum capacitor, the capacitor body is constructed of two metal plates known as electrodes, separated by an insulator. When a DC voltage is applied across the electrodes, the positively charged ions of the metal are attracted to the electrode closest to the negative pole. The negatively charged ions are attracted to the other electrode. This creates an electrical field, which can store electrical energy. This electrical field releases an electric current when it is charged.The M39003/01-8191H capacitor is a molded, two-terminal component with a cylindrical style case and insulated base. It is fabricated using a solid tantalum anode and a manganese dioxide cathode. The cathode casing has a metal surface finish that is either tin-lead (Pb) or tin-silver (Sn/Ag) plated to provide an electrical contact with the component. The manganese dioxide is a non-conductive material. It provides insulation between the anode and the cathode, as well as between the electrodes and the case. The anode and the cathode are connected by a lead and a lead-free solder. The capacitor is then encased to provide thermal and environmental protection.The M39003/01-8191H has several features that make it an attractive choice for a capacitor. It has a low ESR, or equivalent series resistance, which is a measure of the amount of resistance that the capacitor offers to an alternating current. It also features low vibration sensitivity because its construction has a low level of acoustic microphonics. Additionally, its construction grants it a low total harmonic distortion. The tantalum beaded construction also offers a high volumetric efficiency, which is an important feature when component count is a factor. On top of this, its low leakage characteristics make it a great choice for high-precision applications.The M39003/01-8191H capacitor can be used in applications that require high volumetric efficiency and low ESR, including automotive, portable, and consumer electronics. It is used in both high and low voltage applications. It is suitable for use in environments with temperatures ranging from -55°C – +125°C. Additionally, the hermetic seal of the capacitor makes it suitable for use in physically and electromagnetically hostile environments.The M39003/01-8191H capacitor is highly versatile and reliable. Its construction offers excellent capacitance stability and features like a hermetically sealed case and a low total harmonic distortion make it an attractive choice for a wide variety of applications. The high volumetric efficiency and low ESR characteristics of the capacitor make it an excellent choice for applications in automotive, portable, and consumer electronics. With its reliable performance and features, the M39003/01-8191H capacitor is an ideal choice for electronic systems.
