Device Offers High-Temperature Performance to +155 °C With 100 % Power, Derated Linearly to 0 mW at +250 °C.

 

MALVERN, Pa. — April 1, 2014 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced that its PATT precision automotive thin film chip resistor is now available in the 0805 case size. Providing an 85 °C extension in operating temperature range over conventional chip resistors, the PATT features high-temperature operation to +155 °C with 100 % power dissipation, derated linearly to 0 mW at +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 %.

With a load-life stability of ± 0.2 % at 155 °C and full rated power dissipation for 1000 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 industrial and telecommunications equipment.

Offered in 0603 and 0805 case sizes, the PATT thin film resistor series provides a wide resistance range from 2.75Ω to 301 kΩ, with non-E-Series values available. The device features very low noise of < - 30 dB, low voltage coefficients of less than 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 suitable for high-temperature HMP soldering and 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-retardant according to AEC-Q200-001, paragraph 4.0; 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.
