        • Product Name  Tantalum powder
        • Views   70

          Tantalum powder can be divided into two categories. One is capacitor tantalum, the other is metallurgical tantalum.
          Metallurgical tantalum is used for making tantalum foils and tantalum wires.
          Tantalum capacitors for electronic circuits are used in:
            - medical appliances such as hearing aids and pacemakers;
            - automotive components such as ABS, airbag activation, engine management modules, GPS;
            - portable electronics e.g. laptop computers, cellular/mobile phones, video cameras, digital still cameras;
            - other equipment such as DVD players, flat screen TVs, games consoles, battery chargers, power rectifiers, cellular/mobile phone signal masts, oil well probes
