Common Sense Of Tantalum

Tantalum - a bluish strategic metal, called TATALUM in English, has a melting point of over 2900 degrees (second only to tungsten and rhenium) and a Mohs hardness of 6.5 (diamond is 10) and an incredible resistance to Acidity and alkalinity (aqua regia is useless for it, and gold will melt when it touches aqua regia), these properties give tantalum a bad reputation for being difficult to process, but its extremely high dielectric constant (27 is 4 times that of aluminum) The above) and the sintered sponge state and ultra-stable state make electronic component manufacturers endure untold hardships and have to apply it to capacitors, and finally equip them in military electronic equipment.

The U.S. military industry is extremely developed, and it is the largest arms exporter in the world. As long as you are interested in opening up those military electronic equipment, you can see that it is covered with large and small yellow tantalum capacitors (interestingly, the U.S. tantalum capacitors The shells are all yellow, while Japan and others like to use black. The color of the tantalum capacitor shell has nothing to do with its performance. Other tantalum capacitors used in high temperature places have to undergo smoking above 150 degrees, so the yellow shell may be smoked. black, so simply paint it black).
