Featuring a tantalum nitride resistor film on a high-purity alumina substrate, the PAT resistors offer stable film and performance characteristics of 1000 ppm at + 70 °C for 10,000 hours. The devices are optimized for hybrid/electronic controls, energy management, measurement, sensor scales, and stable fixed resistors applications in automotive electronics.
Offered with wraparound terminations in eight case sizes from 0402 to 2512, the PAT series offers a resistance range from 10 Ω to 3 MΩ, with non-standard values available. The resistors feature very low noise of < - 30 dB, low voltage coefficients of < 0.1 ppm/V, and load-life stability of < 0.05 % at 1000 hours at + 70 °C. Power ratings for the series range from 50 mW to 1 W, 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 % relative humidity, and 10 % rated power per MIL-STD-202, method 202. Available with lead (Pb)-free or lead terminations, the resistors are compliant with RoHS directive 2002/95/EC. The devices undergo a 100 % visual inspection per MIL-PRF-55342.
