Automotive Grade Precision Thin Film Chip Resistor Arrays

Vishay Intertechnology announces that the company has enhanced its ACAS 0606 AT and ACAS 0612 AT precision Automotive Grade thin film chip resistor arrays with higher resistance ratios up to 1:100 and operating voltages up to 100 V.

Automotive-grade ACAS AT precision thin film chip resistor arrays featuring enhanced higher resistance ratios and operating voltages for increased design flexibility in voltage divider and signal amplification applications

Provide designers with greater flexibility by allowing them to attain a broader range of output voltages for any input in voltage divider applications. It delivers a five-fold amplification factor increase compared to previous-generation devices.

Offering two and four integrated resistors on one substrate, respectively, the ACAS 0606 AT and ACAS 0612AT lower costs when compared to using multiple high-precision discrete resistors, while at the same time their stable divider ratio improves application stability.
