Vishay Intertechnology, Inc. today announced 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 100 degrees C extension over conventional chip resistors, the Vishay Dale Thin Film PLTT 0603 features a wide operating temperature range from -55 to +230 degrees C, a low absolute TCR down to ± 5 ppm / degrees C, and laser-trimmed tolerances down to ± 0.02 %.
With stable film and performance characteristics of 0.5 % ppm at +175 degrees C 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 resistor features a high-purity ceramic substrate, < 10 µin gold terminations over nickel barrier for high-temperature HMP soldering, and corrosion-resistant special passivation method (SPM) enhancement. The lead (Pb)-free device is RoHS-compliant, halogen-free, and flame-resistant in accordance to UL 94 V-0.
Samples and production quantities of the PLTT resistor in the 0603 case size are available now, with lead times of eight weeks. Pricing for U.S. delivery ranges from $0.40 to $0.55 per piece, depending on tolerance required, in volume quantities.
