Precision high-temperature thin-film chip resistor now automotive qualified

Latest from Vishay comes news that its PLTT precision high-temperature thin-film chip resistor is now available in an AEC-Q200 automotive-qualified 0603 case size. Providing a greater than 100C extension over conventional chip resistors, the PLTT 0603 features a wide operating temperature range from -55C to +230C, a low absolute TCR down to ±5ppm/C, and laser-trimmed tolerances down to ±0.02%. With stable film and performance characteristics of 0.5% ppm at +175C for 2,000 hours at 50% of rated power, the resistor released today is optimized for the low-noise single-signal processing required to compensate for low offset and temperature drift in high-temperature automotive environments, such as exhaust sensing. The device will also deliver reliable performance in down-hole applications, high-precision oil and gas exploration, and telecommunications and industrial equipment. The PLTT 0603 provides a wide resistance range from 250ohm to 150kohm, with nonstandard values available. The devices feature very low noise of <-30dB, a low voltage coefficient of 0.1ppm/V, power dissipation ratings from 150mW to 1W, and 75V to 200V maximum working voltages. The PLTT Series devices are also available in the 0805, 1206, 2010, and 2512 case sizes with resistance values up to 3Mohm, says the company.
