Sprague is well known for developing the first tantalum capacitors and introducing the first surface-mount tantalum chip capacitors. This commitment to innovation is maintained today through the wide Vishay Sprague product line, which includes molded and conformal-coated surface-mount tantalum capacitors, leaded tantalum capacitors, and hermetically sealed tantalum capacitors. Vishay Sprague tantalum capacitors are used worldwide in a variety of applications, from cellular telephones and computers to military and aerospace electronics.

Vishay's acquisitions of capacitor manufacturers including Tansitor and North American Capacitor Company (Mallory capacitors) further strengthened its product portfolio. Vishay has consolidated its wet tantalum capacitors under the Vishay Sprague brand name. Vishay is the number one manufacturer of wet tantalum capacitors worldwide.
