The leakage current and break-down voltage of the dielectric is not deteriorated, thus leading to the introduction of a new line of high-voltage tantalum
polymer capacitors with long-term reliability [10-12].
In all the composites, the grains are smaller in comparison to pure nanocrystalline tantalum
. The smallest grains have the composites reinforced with [Y.sub.2][O.sub.3] and Zr[O.sub.2].
Based on the information from Figure 2 spectra one may note that oxygen (O 1s, O KLL), carbon (C 1s), phosphorus (P 2s, P 2p), calcium (Ca 2p, Ca 3p, Ca 3s), copper (Cu 2p), and tantalum
(Ta 4f, Ta 4d, Ta 5s, Ta 5p) were found out.
The primary feature responsible for limiting the height and package efficiency of tantalum
capacitors is their conventional package, but the problem with scaling down conventional tantalum
capacitors into embedded tantalum
capacitors is twofold: efficiency and manufacturability.
The specific type of tantalum
powder used also plays a large role in the electrical performance and robustness of these components.
Designed for the toughest conditions: The new tantalum
range has been specifically developed for use with hot, highly corrosive liquids.
The company says it had success pressuring its tantalum
suppliers into a third party because Apple is the leading user of the metal worldwide.
During this period he has overseen the development of a Tantalum
Mine in Mozambique and the acquisition and evaluation of the Mrima Hill Rare Earth and Niobium Project in Kenya.
Several classes of alloys were tested, including stainless steel (316L (UNS S31603)), nickel-based alloy (C276 (UNS N10276)), titanium alloys (Ti 6-4 (UNS R56400) and Ti 6-2-4-6 (UNS R56260)), and 316L surface-alloyed with tantalum
I use tantalum
capacitors as an example because, a few years ago, there was what many trade publications deemed "a shortage of tantalum
capacitors" that was incorrectly attributed to a shortage of tantalum
Congress originally mandated the rules in 2010, with the intention of reducing use of key minerals such as gold, tin, tungsten and tantalum
as a source of financing for armies battling in the Democratic Republic of Congo and other neighboring countries.
