Drill heads and downhole assemblies face temperatures that destroy ordinary electronics long before a well reaches depth. Vishay's PHT high stability precision resistors are rated for powered operation to 215 °C, with tolerances as tight as ± 0.05 % and sulfur resistance that withstands the sour gas common downhole. That stability keeps position, flow, and height
measurement circuitry accurate even as drilling conditions intensify, giving operators reliable data from the harshest part of the wellbore.
Behind every downhole reading is The DNA of tech.®
With over six decades of experience developing components designed to withstand high temperature and humidity conditions, Vishay's components are engineered to ensure exceptional reliability, featuring such qualifications as AEC-Q100, AEC-Q101, and AEC-Q200.
