PAT Series Thin Film Chip Resistors

Vishay/Thin Film's PAT series of AEC-Q200-qualified precision automotive thin film chip resistors have an ESD rating of 2 kV. Designed to meet automotive industry requirements for temperature and humidity while offering consistent repeatability and stable performance, the devices feature a low standard TCR of ±25 ppm/°C and laser-trimmed tolerances down to ±0.1%.

Featuring a tantalum nitride resistor film on a high-purity alumina substrate, PAT resistors offer stable film and performance characteristics. The devices are optimized for hybrid/electronic controls, energy management, measurement, sensor scales, and stable fixed resistor applications in automotive electronics.

These resistors have wraparound terminations and are offered from DigiKey in three case sizes: 0603, 0805, and 1206. The PAT series is offered with resistance ratings from 10 Ω to 604 kΩ 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 2000 hours at +70°C. Power ratings for the series range from 150 mW to 400 mW, 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.
