Development history of AVX tantalum capacitors and elements of tantalum capacitors

AVX is a rare metal tantalum capacitor, tantalum processing, put into fine powder and tantalum, and other media formed by sintering. The present technology has two kinds of dry powder molding method and wet powder molding method. Due to the inherent nature of tantalum tantalum capacitor, with good stability, not change with changes in the environment, can do great values and other characteristics, some characteristics in some aspects with ceramic capacitors can not be compared, therefore cannot be used in many ceramic capacitor circuit on tantalum capacitors are widely used.

钽电容的制作过程：用钽粉压制成型，经过烧结后作为电容器的阳极，后经过化学方法在其表面生成氧化膜作为介质，而在表面生成二氧化锰作为阴极由于使用金属钽做介质，不需要像普通电解电容那样使用电解液，另外，钽电容不需像普通电解电容那样使用镀了铝膜的电容纸烧制，所以本身几乎没有电感，但同时也限制了它的容量此外，钽电容内部没有电解液，很适合在高温下工作它被应用于大容量滤波的地方，像cpu插槽附近就可以看到钽电容的身影，多同陶瓷电容，电解电容配合使用或是应用于电压、电流不大的地方.

The production process of tantalum capacitors: tantalum powder press molding after sintering as the anode of the capacitor, after chemical method on the surface oxide film as the medium, and on the surface of MnO2 as cathode is generated due to the use of tantalum metal as a medium, do not need to use as the electrolyte, like ordinary electrolytic capacitors and tantalum capacitors without burning the use of aluminum plated paper capacitor as ordinary electrolytic capacitor, so its almost no inductance, but also limited in its capacity, no internal electrolyte tantalum capacitor, it is suitable for the work it has been applied to large capacity filter in high temperature, such as near the CPU slot, you can see the tantalum capacitor figure. Many with ceramic capacitors, electrolytic capacitors use or is applied to voltage and current is not in place.

钽电容的优点及作用：稳压防治电压抖动及滤波的作用 2.由于体积小容量大，适用于较小空间 3. 随温度的升高，稳定性要优于瓷片电容

The advantages and effects of tantalum capacitors: voltage control voltage jitter and filtering effect of 2 due to the small size of large capacity, suitable for small space 3 with the increase of temperature, the stability is better than that of ceramic capacitors
