Automotive Qualified Thin Film Chip Resistor Now Available in 0402 and 1206 Case Sizes

Vishay Intertechnology, Inc. has extended its PATT precision automotive thin film chip resistor family with devices in the 0402 and 1206 case sizes. The devices are available with gold-plated terminals for conventional solder assembly and conductive glueable board mount technologies. Providing an 85 °C extension in operating temperature range over most conventional chip resistors, the thin film PATT features high-temperature operation to +155 °C with 100 % power dissipation, derated linearly to +250 °C. The AEC-Q200-qualified device offers a low absolute TCR down to ± 25 ppm/°C and laser-trimmed tolerances down to ± 0.1 %. The part features an intrinsic moisture-protected resistor element built on tantalum nitride technology.

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 such as gain setting in ultra-low noise and precision analog digital processors and high-gain audio amplifiers; under-the-hood automotive applications; high-precision oil and gas exploration; industrial in-line testers; metering; and telecommunications and industrial equipment.

Offered in 0402, 0603, 0805, and 1206 case sizes, the PATT provides a wide resistance range from 1 W to 1 MW. The device features very low noise of < -30 dB, a low voltage coefficient of 0.1 ppm/V, power dissipation ratings from 50 mW to 400 mW, and 75 V to 200 V maximum working voltages.

The resistor features a high-purity ceramic substrate, 10 min (0.254 mm) gold terminations over nickel barrier for high-temperature HMP soldering or conductive gluing bonding, and withstands ESD to 2 kV per AEC-Q200 Class 1C. The device 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 is halogen-free, RoHS-compliant, and Vishay Green.

Samples and production quantities of the PATT resistor in the 0402 and 1206 case sizes are available now, with lead times of eight weeks. Pricing for U.S. delivery ranges from $0.26 to $0.45 per piece, depending on case size and tolerance, in 1,000-piece quantities.
