Tantalum capacitors Tantalum capacitors are full name tantalum electrolytic capacitors, which are also a kind of electrolytic capacitors. They use metal tantalum as the medium. Unlike ordinary electrolytic capacitors, they do not use electrolyte. Tantalum capacitors do not need to use aluminum-plated capacitors like ordinary electrolytic capacitors. Paper winding has almost no inductance, but this also limits its capacity. In addition, since there is no electrolyte inside the tantalum capacitor, it is very suitable for working at high temperatures. Tantalum capacitors are characterized by long life, high temperature resistance, high accuracy, and excellent performance in filtering high frequency harmonics. In the working process of tantalum electrolytic capacitors, it has the performance of automatically repairing or isolating the defects in the oxide film, so that the oxide film medium can be strengthened at any time and restore its due insulation ability, without being subjected to continuous cumulative damage. This unique self-healing performance guarantees its long life and reliability advantages. Direct plug-in tantalum capacitors Solid tantalum capacitors have excellent electrical properties, a wide operating temperature range, various forms, and excellent volumetric efficiency. They have their unique characteristics: the working medium of tantalum capacitors is a very thin layer of pentoxide formed on the surface of tantalum metal. Tantalum film. The oxide film dielectric of this layer is combined with one end of the capacitor to form a whole and cannot exist alone. Therefore, it has a very high working electric field intensity per unit volume, and has a particularly large capacitance, that is, a very high specific capacity, so it is particularly suitable for miniaturization.
