The Perspective:
For extreme high-temperature environments, the new Vishay Sfernice PHT high-precision SMD wraparound thin film chip resistors feature an operating temperature range from - 55 °C to + 215 °C, with a maximum storage temperature up to + 230 °C, an industry-first for any resistor built on thin film technology. Even with this high temperature rating, the devices feature a load life stability of 0.5 % after 1000 hours at 215 °C, as well as tight TCR and tolerance values. Typical TCR for the new resistors is 25 ppm/°C, with available tolerances down to 0.05 %. An enlarged termination option is available for applications with extraordinary power dissipation requirements.
