VISHAY SFERNICE

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

Vishay Sfernice products include fixed resistors in wirewound, metal film, thick film, and thin film technologies, as well as a significant range of variable resistors. The variable product range is extensive and encompasses variable resistors 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 multi-turn styles are offered. The range of motion transducers includes single-turn, rotational, and linear, and these products are used in military, aerospace, automotive, off-road, medical, measurement, robotics, nuclear, and general industrial applications. For applications in harsh environments requiring a very long life and a great number of cycles, our product line-up includes a family of non-contacting devices using Hall effect technology.

Vishay Sfernice long-life panel potentiometers, offering lifetimes from 500,000 to 2 million cycles, increase reliability in critical applications, reduce the need for replacement parts, and lower maintenance costs. Vishay Sfernice also offers a wide range of power thick film resistors that can be mounted on heatsinks or PCBs. Their available power dissipation ranges from 5 W to upwards of 800 W. These products typically exhibit a high power-to-volume/weight ratio, no inductance, low tolerance, wide ohmic range, and high 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 undergo stringent testing both during and after manufacturing. Sfernice is a brand associated with the manufacturing of electronic components, including resistors, variable resistors (potentiometers), and motion transducers.

1. Resistors (Fixed Resistors): Sfernice, as part of Vishay, produces fixed resistors that are used in electronic circuits to limit or control the flow of electric current. These resistors come in various types, including film resistors and wirewound resistors, and they are chosen based on factors such as resistance value, power rating, and tolerance.

2. Variable Resistors (Potentiometers): Sfernice manufactures potentiometers, which are variable resistors that can be adjusted to change the resistance in a circuit. Potentiometers are often used for volume controls, voltage dividers, and other applications where variable resistance is required. Sfernice's potentiometers are designed to provide precise and reliable control over resistance.

3. Motion Transducers: Motion transducers, in the context of Sfernice, likely refer to devices that can convert mechanical motion into electrical signals or vice versa. This can include various types of sensors or transducers designed to detect and measure motion, such as linear and rotary position sensors. These components are used in applications where monitoring or control of mechanical movement is essential.
