Vishay Intertechnology Enhances Precision Thin Film Chip Resistor Arrays With Tighter Tolerances and Temperature Coefficients for Automotive and Industrial Applications
MALVERN, Pa. — May 16, 2013 —Vishay Intertechnology, Inc. (NYSE: VSH) today announced that the company has enhanced its ACAS 0606 AT and ACAS 0612 AT precision thin film chip resistor arrays with tighter absolute tolerance, relative tolerance, and relative TCR for the new S, T, and U accuracy grades. Offering two and four integrated resistors on one substrate, respectively, the ACAS 0606 AT and ACAS 0612 AT lower costs when compared to using multiple high-precision discrete resistors, while at the same time their stable divider ratio improves the stability of the application.
For increased accuracy, the Vishay Beyschlag ACAS 0606 AT and ACAS 0612 AT combine their high-temperature operation to +155 °C with tight absolute tolerance of ±0.1 %, relative tolerance of ±0.05 %, absolute TCR down to ±10 ppm/K, and relative TCR down to ±5 ppm/K. The devices offer resistance from 47 Ω to 150 kΩ, with equal or different resistor values, and maximum resistance ratio of 1:20.
In addition to excellent high-temperature performance, the ACAS 0606 AT and ACAS 0612 AT are extremely robust against harsh environmental conditions and provide superior moisture resistivity of l?R/Rl < 0.5 % at +85 °C and 85 % relative humidity for 1000 hours. The devices offer a 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, and feedback circuit applications that require extraordinarily stable fixed resistor ratios. Typical applications will include automotive electronics, including engine control units, gear box controls, safety, power supply electronics, body electronics, braking systems, climate control, steering technology, and lighting; and industrial electronics, such as energy management, measurement control, sensors, scales, and precision amplifiers.
Samples and production quantities of the enhanced resistor arrays are available now, with lead times of six to eight weeks.
