Vishay / Sfernice produces fixed and variable resistors in most of the existing technologies. With its wide range and its capability to manufacture standard as well as custom designed products, Vishay / Sfernice covers applications in all market sectors. Included in their product line are encoders, potentiometers, power resistors, resistor networks and arrays, SMD, and thin film resistors.
Vishay / Sfernice P16S Knob Potentiometer with Switch features low profile, small size, potentiometer in knob, and is IP67 sealed. Vishay / Sfernice P16S Knob Potentiometer with Switch is a revolutionary concept in panel mounted potentiometers. This unique design consists of a knob driving and incorporating a cermet potentiometer. Only the mounting hardware and terminals are situated on the back side of the panel producing a minimum required clearance. Applications for the P16S Knob Potentiometer with Switch include military, industrial, and medical.
Vishay/Sfernice has expanded the LPS series Heatsink Mounted Power Resistors to include the LPS1100 Thick Film Power Resistors that
feature high power of 1100 W, a wide resistance range of 1 Ω to 1.3 kΩ
series E24, easy mounting, and non-inductance. Vishay LPS1100 Thick
Film Power Resistors are ideal for converters, inverters, and medical
The Vishay / Sfernice LPS Series Heatsink Mounted Power Resistors
offer either 300W, 600W, or 800W at 85ºC bottom case temperature and a
wide resistance range: 0.3Ω to 900kΩ. Non inductive and easily mounted,
the LPS Series features low thermal insulation to UL 94 V0. Vishay / Sfernice LPS Series Heatsink Mounted Power Resistors are thick film
technology and are RoHS compliant to directive 2002/95/EC. In addition, these non-inductive resistors are in a compact 57mm x 60mm package.
