Vishay Intertechnology Inc. introduced a new series of precision thin film chip resistor arrays featuring gold terminations for conductive gluing. Offering two integrated resistors on one substrate, the ACAS 0606 ATAU resistor array combines high-temperature operation to 155 °C with relative tolerance down to ±0.05 % and relative TCR down to ±5 ppm/K.
ACAS 0606 ATAU resistor arrays enable significantly more accurate performance than two high-precision discrete resistors, and their small 1.5 mm by 1.6 mm package enables the design of high-density circuits. The devices offer two equal or different resistance values from 100 Ω to 150 kΩ, with a maximum resistance ratio of 1:20.
In addition to excellent high-temperature performance, the ACAS 0606 ATAU series is extremely robust against harsh environmental conditions and provides superior moisture resistivity of lΔR/Rl < 0.5 % at 85 °C and 85 % relative humidity for 1,000 hours. The device offers 1000 V ESD capability, a 75 V operating voltage, and maximum rated dissipation to 0.125 W per element. For automotive applications, the resistors are qualified according to AEC-Q200.
The new resistor arrays are ideally suited for precision analog circuits, voltage dividers, feedback circuits, and signal conditioning applications that require extraordinarily stable fixed resistor ratios. Typical application fields will include automotive electronics, including engine control units, gear box controls, safety, power supply electronics, body electronics, braking systems, and lighting; and industrial electronics, such as energy management, measurement, and control technology.
Samples and production quantities of the ACAS 0606 ATAU resistors are available now, with lead times of 8 to 10 weeks. Pricing for U.S. delivery starts at $0.50 per piece.
