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.

鉭電容的制作過程：用鉭粉壓制成型，經過燒結后作為電容器的陽極，后經過化學方法在其表面生成氧化膜作為介質，而在表面生成二氧化錳作為陰極由于使用金屬鉭做介質，不需要像普通電解電容那樣使用電解液，另外，鉭電容不需像普通電解電容那樣使用鍍了鋁膜的電容紙燒制，所以本身幾乎沒有電感，但同時也限制了它的容量此外，鉭電容內部沒有電解液，很適合在高溫下工作它被應用于大容量濾波的地方，像cpu插槽附近就可以看到鉭電容的身影，多同陶瓷電容，電解電容配合使用或是應用于電壓、電流不大的地方.

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.

鉭電容的優點及作用：穩壓防治電壓抖動及濾波的作用 2.由于體積小容量大，適用于較小空間 3. 隨溫度的升高，穩定性要優于瓷片電容

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
