This document describes PAT brand precision automotive thin film chip resistors, which are AEC-Q200 qualified and have a 2 kV ESD rating. These resistors utilize self passivated enhanced tantalum nitride resistor film to provide superior performance in moisture resistance, electrostatic discharge, voltage coefficient, power handling, and resistance stability.
The PAT thin‑film precision automotive chip resistors from Vishay feature self‑passivated enhanced tantalum nitride film, providing superior moisture resistance, low voltage coefficient and excellent power handling. They are supplied in wrap‑around lead terminations with an adhesion layer, nickel barrier and lead‑free solder coating.
The datasheet lists electrical specifications such as resistance range, tolerance, TCR, working voltage and temperature range, as well as environmental test results that meet AEC‑Q200 requirements. Various case sizes (0402‑2512) and corresponding power ratings are also provided.
| Resistance range | 10 Ω to 3 MΩ |
|---|---|
| Temperature coefficient (TCR) | ± 25 ppm/°C to ± 100 ppm/°C |
| Tolerance | ± 0.1 % to ± 1.0 % |
| Working voltage | 75 V to 200 V |
| Operating temperature range | -55 °C to +150 °C |
| Voltage coefficient | < 0.1 ppm/V |
| Power rating (0603 case) | 150 mW |
The PAT resistors are AEC‑Q200 ESD rated class 1C at 2 kV.
They are offered in eight case sizes: 0402, 0603, 0805, 1206, 1505, 2010, 2208 and 2512.
The absolute TCR is between ± 25 ppm/°C and ± 100 ppm/°C.
The resistors operate from 75 V up to 200 V.
