Vishay Dale Thin Film PLTT 0603 thin-film chip resistor

Vishay Intertechnology’s PLTT precision high-temperature thin-film chip resistor is now available in an AEC-Q200 automotive-qualified 0603 case size. Providing >100°C extension over conventional chip resistors, the Vishay Dale Thin Film PLTT 0603 features an operating temperature range from -55 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 is optimised for the low-noise single-signal processing required to compensate for low offset and temperature drift in high-temperature automotive environments. The device will also perform in down-hole applications, high-precision oil and gas exploration, and telecommunications and industrial equipment.

The product provides a resistance range from 250 Ω to 150 kΩ, with non-standard values available. It features 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 to 200 V maximum working voltages. Devices are also available in the 0805, 1206, 2010 and 2512 case sizes with resistance values up to 3 MΩ.

The resistor features a high-purity ceramic substrate, <10 µin gold terminations over a nickel barrier for high-temperature HMP soldering and corrosion-resistant special passivation method (SPM) enhancement. The lead-free device is RoHS compliant, halogen-free and flame resistant.
