The Sfernice name has been well known throughout Europe and in other regions for many years. Today, Vishay Sfernice products include resistors, potentiometers, and motion transducers. They include both standard and custom-custom designed components, and are used in a wide variety of applications in many market sectors.

Vishay Sfernice products include fixed resistors in wirewound, power oxide, thick film, thin film, and foil technologies, as well as a significant array of variable resistors. The variable resistor product range is extensive and encompasses potentiometers, trimmers, and motion transducers, many of which are approved to CECC/UTE/NF or MIL specifications. Cermet and conductive plastic technologies are deployed, and single or multiturn styles are offered. The range of motion transducers includes both single-turn, rotational, and linear, and these products are used in military, aerospace, automotive, medical, measurement, robotics, nuclear, and general industrial applications.

A new Vishay Sfernice series of thick film power resistors has been developed, many of which can be mounted onto a heatsink to increase power dissipation. These products typically exhibit high a power-to-volume ratio, low tolerance, and excellent overload capabilities. High-reliability components are a key feature of the Vishay Sfernice product line. Techniques developed to manufacture these components are jointly evaluated by the National Space Study Center (CNES) and ESA/SCC. The devices must undergo stringent testing both during and after manufacture.
