Vishay Intertechnology PLTT Precision High-Temperature Thin Film Chip Resistor Now Available in Automotive-Qualified 0603 Case

Vishay PLTT

Vishay Intertechnology 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 °C extension over conventional chip resistors, the Vishay Dale Thin Film PLTT 0603 features a wide operating temperature range from -55 °C to +230 °C, a low absolute TCR down to ± 5 ppm/°C, and laser-trimmed tolerances down to ± 0.02 %.

With stable film and performance characteristics of 0.5 % ppm at +175 °C for 2000 h 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 250 Ω to 150 kΩ, with non-standard values available. The devices feature very low noise of < -30 dB, a low voltage coefficient of 0.1 ppm/V, power dissipation ratings from 150 mW to 1 W, and 75 V to 200 V maximum working voltages. PLTT series devices are also available in the 0805, 1206, 2010, and 2512 case sizes with resistance values up to 3 MΩ.

The PLTT 0603 resistor feature 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 sizes are available now, with lead times of eight weeks.
