PAT Series Thin Film Chip Resistors


Vishay's PAT series meets automotive industry requirements for temperature and humidity

Vishay/Thin Film's PAT series of AEC-Q200-qualified precision automotive thin film chip resistors have an ESD rating of 2kV. 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 ±25ppm/°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 Digi-Key in three case sizes: 0603, 0805, and 1206. The PAT series is offered with resistance ratings from 10Ω to 604kΩ with non-standard values available. The resistors feature very low noise of <-30dB, low voltage coefficients of <0.1ppm/V, and load-life stability of <0.05% at 2000 hours at +70°C. Power ratings for the series range from 150mW to 400mW, and voltage ratings are from 75V to 200V 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.
