Vishay Beyschlag

Precision Thin Film Chip Resistor Array

Superior Moisture Resistivity

ACAS 0606 AT and ACAS 0612 AT precision automotive

grade thin film chip resistor arrays with convex terminations

combine the proven reliability of discrete chip resistors with

the advantages of chip resistor arrays. Defined tolerance

matching and TCR tracking make this product perfectly

suited for applications with outstanding requirements

towards stable fixed resistor ratios. Four equal resistor

values or two pairs are available for the ACAS 0612 AT,

whereas the ACAS 0606 AT is available either with two equal

or two different resistor values. Find out more about Vishay’s

FEATURES

• Superior moisture resistivity, |ΔR/R| < 0.5 %

(85 °C; 85 % RH; 1000 h)

• Rated dissipation P

resistor

• ESD capability 1000 V, human body model

• TCR tracking down to 10 ppm/K (± 5 ppm/K) and tolerance

matching down to 0.1 % (± 0.05 %)

• AEC-Q200 qualified

• Compliant to RoHS directive 2002/95/EC

APPLICATIONS

• Precision analogue circuits

• Voltage divider

• Feedback circuits

• Signal conditioning

Notes

required to replace discrete resistors with a temperature coefficient of resistance of ± 5 ppm/K. Furthermore, in order to achieve the same

tolerance of ± 0.05 % of individual resistors, an array requires a matching of 0.1 %.
