High-temperature chip resistor is AEC-Q200 qualified

Vishay Intertechnology's PLTT precision high-temperature thin film chip resistor is now available in an AEC-Q200 automotive-qualified 0603 case size. The PLTT 0603 resistor features a wide operating temperature range from -55 to +230°C, 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 +175°C for 2,000 hours at 50% of rated power, the resistor released today is optimised 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 250Ω to 150kΩ, with nonstandard values available. The devices feature very low noise of less than -30dB, a low voltage coefficient of 0.1ppm/V, power dissipation ratings from 150mW to 1W and 75 to 200V maximum working voltages. PLTT series devices are also available in the 0805, 1206, 2010 and 2512 case sizes with resistance values up to 3MΩ.

The PLTT 0603 resistor features a high-purity ceramic substrate, less than 0.254µm gold terminations over nickel barrier for high-temperature HMP soldering, and corrosion-resistant special passivation method 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.
