Capacitor grade tantalum wire manufacturers

What is a tantalum capacitor?

Tantalum capacitors use tantalum metal and solid manganese dioxide electrolyte, providing high capacitance in a compact size. Normal electrolytic capacitors, often aluminum-based with liquid electrolyte, offer a wider range of capacitance. Tantalum capacitors are polarized, unlike some electrolytic capacitors.

Where can I buy a tantalum refractory capacitor?

Admat, Inc., located in Norristop, PA, distributes tantalum hybrid capacitors as well as capacitor lead sealing. It also offers other refractory metal products and parts.

Are tantalum capacitors susceptible to DC bias?

Tantalum capacitors are not susceptible to DC bias. Finally, as mentioned above, all of the tantalum capacitors’ parameters are very stable over a wide range of temperatures, from -55 to 125°C, and even up to 175°C. MLCC devices have many different grades for different temperature groupings, such as X5R, X7R, and NP0.

Is GAM capacitor wire grain stabilized or un-doped?

GAM’s capacitor wire can be un-doped or grain stabilized and has followed the same ISO controlled process since 1993. GAM produces high purity metallurgical (met) grade powder up to 99.995% purity on a metal basis.

What are the different types of capacitor grade powder?

Global Advanced Metals (GAM) produces three types of capacitor grade powder: Angular, Nodular and Flake. The angular or EB type powders are manufactured using an electron beam melting process. These powders contain both angular and flake shaped particles, which have been agglomerated to a specified surface area and capacitance range.
