思碧（Sprague）因开发出第一个钽电容器以及引入了第一个表面安装型钽芯片电容器而闻名。 现今威世思碧Sprague仍通过广泛的产品线保持着创新的承诺，这些产品包括模制和保形涂层表面安装钽电容器、引线型钽电容器和密封钽电容器。威世思碧Sprague的钽电容器广泛应用于世界范围内的各种应用，从手机和电脑到军事与航空电子无所不在。

威世对于电容器制造商Tansitor和北美电容器公司（Mallory capacitors）的收购进一步增强了其产品系列。 威世已将其所有的湿钽电容器归在威世思碧（Vishay Sprague）品牌之下。 威世公司全球世界排名第一的湿钽电容器制造商。

Vishay Sprague is well known for having invented the first tantalum capacitors and the first surface-mount tantalum chip capacitors. Vishay Sprague continues this commitment to innovation today through the ongoing development of higher performance tantalum capacitors in a wide range of sizes.

With its MicroTan® family, which is built on a unique assembly process, Vishay Sprague offers the smallest tantalum capacitors on the market with the highest capacitance and voltage ratings. The high-energy HE3 wet tantalum capacitor covers the high side of the capacitance spectrum for wet tantalum capacitors, while other types of wet tantalum capacitors can be found in such extreme applications as military, avionics, space, and oil-drilling.

Vishay Sprague has the broadest range of tantalum capacitors offered by any manufacturer with devices that also include conformal coated and molded surface-mount styles, as well as both radial and axial through-hole products, covering a wide range of automotive, consumer, industrial, and telecommunications as well as very high-performance applications.

Vishay acquired its tantalum capacitor division from Sprague in 1992, which was founded in 1926 by Robert Sprague, founder of the “tone control” capacitor. Vishay subsequently reinforced its position in the marketplace by acquiring tantalum operations from brands like Mepco, Roederstein, Tansitor, North American Capacitor Company (Mallory capacitors) and more recently, Kemet and Arcotronics wet tantalum products. Vishay is the number one manufacturer of wet tantalum and conformal-coated capacitors worldwide.
