The patch processing factory has encountered a very difficult problem recently, and it is related to the vital interests of customers, that is, the price increase of components. From the new crown epidemic to the cold wave in Texas some time ago, the prices of components under the pressure of various factors have skyrocketed, especially the tantalum capacitor component. Why are tantalum capacitors like this? Combining the actual situation in the smt patch, today we will analyze it from the component itself!

        Tantalum Electrolytic Capacitors Tantalum electrolytic capacitors have excellent performance. It is a product with a small volume but a larger capacitance among all capacitors. Therefore, it is easy to make small and chip components suitable for surface mounting.

        The tantalum capacitors currently produced include sintered solids, foil-wound solids, and sintered liquids. The sintered solids account for more than 95% of the current total output, and the non-metallic sealing resin package is the main body.

        The working environment medium of tantalum electrolytic capacitor is a very thin tantalum pentoxide film formed on the surface of tantalum metal material. The oxide film dielectric of this layer is integrated with one end pole of the capacitor and cannot exist alone. Therefore, the capacitance per unit volume is very large, that is, the specific capacity is very high, so it is particularly suitable for miniaturization. During the working process of the tantalum electrolytic capacitor, it has the performance of automatically repairing or isolating oxide film defects, so that the oxide film medium can be strengthened at any time, and its proper insulation ability can be restored without continuous cumulative damage. This unique self-healing technology performance guarantees its long life and reliability advantages.

        According to the shape, tantalum electrolytic capacitors can be divided into slice rectangular and cylindrical. According to the packaging method, electrolytic capacitors can be divided into chip type, molded package type and end cap type.

        Because of the excellent capacitance and very small size, in the era of smart devices becoming more and more miniaturized, there is no doubt that the unique advantages of tantalum capacitors and the convenience of the process in the PCB proofing patch have caused the Today its prices are flying all the way.
