PAT series

Vishay Intertechnology Inc. rolls out a range of PAT resistors available in eight case sizes from 0402 to 2512. The AEC-Q200-qualified precision automotive thin-film chip resistors with an ESD rating of 2kV are tailored to meet new automotive industry requirements for temperature and humidity. They offer consistent repeatability and stable performance and the devices feature a low standard TCR of ± 27;5 ppm/°C and laser-trimmed tolerances down to ± 07;.1 per cent.

Featuring a tantalum nitride resistor film on a high-purity alumina substrate, the PAT resistors offer stable film and performance characteristics of 1000ppm at +70°C for 10,000 hours. The devices are optimised for hybrid/electronic controls, energy management, measurement, sensor scales, and stable fixed resistor applications in automotive electronics.

Offered with wraparound terminations in eight case sizes from 0402 to 2512, the PAT series offers a resistance range from 10Ω to 3MΩ, with nonstandard values available. The resistors feature very low noise of <—30 dB, low voltage coefficients of <0.1ppm/V, and load-life stability of <0.05 per cent at 1,000 hours at + 70 °C. Power ratings for the series range from 50mW to 1W, and voltage ratings are from 75 V to 200 V over an operating temperature range of—55°C to +150°C.

The PAT devices are resistant to moisture at +85°C, 85 per cent relative humidity, and 10 per cent rated power per MIL-STD-202, method 202. They are available with lead free or lead terminations, the resistors and are RoHS directive 2002/95/EC compliant. The devices undergo a 100 per cent visual inspection per MIL-PRF-55342.
