Datasheet

The PATT precision automotive thin film chip resistor, from Vishay Intertechnology, is now available in the 0805 case size. Featuring high-temperature operation to +155°C with 100% power dissipation, derated linearly to 0 mW at +250°C, the company claims the device provides a nearly 85°C extension in operating temperature range over conventional chip resistors.

The AEC-Q200-qualified device offers a low absolute TCR down to ± 25 ppm/°C and laser-trimmed tolerances down to ± 0.1 %. With a load-life stability of < 0.2 % at 155 °C and full rated power dissipation for 1,000 hours, the Vishay Dale Thin Film resistor released today is optimized for the low-noise analog signal processing required to compensate for low offset and temperature drift in high-temperature environments, including under-the-hood automotive applications; high-precision oil and gas exploration; and telecommunications and industrial equipment.

Offered in 0603 and 0805 case sizes, the PATT thin film resistor provides a wide resistance range from 2.75 Ω to 301 kΩ, with non-E-series values available. The device features very low noise of < -30 dB, a low voltage coefficient of 0.1 ppm/V, power dissipation ratings from 150 mW to 200 mW, and 75 V to 100 V maximum working voltages.

The PATT thin film resistor series features a high-purity ceramic substrate, 10 μin (0.254 μm) gold terminations over nickel barrier for high-temperature HMP soldering or conductive glueing bonding, and withstands ESD to 2 kV per AEC-Q200 Class 1C. The PATT thin film resistor series is moisture resistant according to MIL-STD-202, method 106; flame-resistant according to AEC-Q200-001; sulfur-resistant per ASTM B809-95 humid vapor test; and 100 % visually inspected per MIL-PRF-55342.

The PATT thin film resistors are halogen-free and are RoHS-compliant without exemptions.
