Vishay 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. Typical applications will include industrial electronics, such as energy management, measurement control, sensors, scales and precision amplifiers; and automotive electronics, including engine control units, gearbox controls, safety, power supply electronics, body electronics, braking systems, climate control, steering technology and lighting.
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 arrays 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. They offer resistance from 47 Ω to 150 kΩ, with equal or different resistor values, and maximum resistance ratio of 1:20.
The ACAS 0606 AT and ACAS 0612 AT are robust against harsh environmental conditions and provide superior moisture resistivity of lR/Rl < 0,5% at +85°C and 85% relative humidity for 1000 hours. They offer 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 arrays are ideally suited for precision analog circuits, voltage dividers and feedback circuit applications that require highly stable, fixed resistor ratios.
