Vishay Intertechnology, Inc. introduced a new series of AEC-Q200-qualified, high-precision dual-in-line thin film resistor networks. The Vishay Dale Thin Film AORN series features low TCR tracking of ± 5 ppm/°C, tight ratio tolerances to ± 0.05 %, and excellent long-term ratio stability of 0.015 % after 1,000 hours at +155 °C. For improved ESD and moisture protection, the resistor networks are constructed with a tantalum nitride resistor film on a high-purity alumina or ceramic substrate.
AORN series devices are available in two configurations: as four equal-value resistors ranging from 1 kW to 100 kW and as two resistor dividers in the same package with ratios from 1:1 to 1:100. The resistor networks feature a rugged molded 50 mil pitch construction and narrow (0.150 in) 8-pin SOIC packages, in accordance with JEDEC MS-012. The devices offer a typical power rating of 100 mW per resistor element.
The integrated construction of AORN resistor networks allows for higher precision over discrete SMT chips, making the devices ideal for precision voltage dividers, op amps, and battery management applications. Typical end products will include automotive, telecommunications, industrial, process control, and medical instrumentation. Per AEC-Q200, the resistor networks are rated for ESD to 2 kV at > 10 kW. The devices feature extremely low noise of < -30 dB and voltage coefficients of < 0.1 ppm/V, and they operate over a wide temperature range of -55 °C to +155 °C. AORN series devices are RoHS-compliant and halogen-free, and they pass the sulfur resistance test per ASTM B 809.
Samples and production quantities of the new resistor networks are available now, with lead times of eight weeks for larger orders. Pricing for U.S. delivery starts at $0.35 per piece in volume quantities and varies by ratio tolerance.
