Automotive Precision Thin Film Chip Resistor Array

ACAS 0612 Automotive thin chip resistor arrays with convex

terminations combine the proven reliability of discrete

automotive chip resistors with the advantages of chip resistor

arrays. Defined tolerance matching and TCR tracking makes

this product perfectly suited for applications with outstanding

requirements towards stable fixed resistor ratios. A small

package enables the design of high density circuits in

combination with reduction of assembly costs. Four equal

resistor values or two pairs are available.

FEATURES

• Tested according AEC-Q200

• 155 °C film temperature

• 1000 V ESD stability

• Advanced thin film technology

• Two pairs or four equal resistor values

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

matching down to 0.1 % (± 0.05 %)

and lead containing soldering processes

APPLICATIONS

• Precision analogue circuits

• Voltage divider

• Feedback circuits

• Signal conditioning

Notes

circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not exceeded. Furthermore, a high

level of ambient temperature or of power dissipation may raise the temperature of the solder joint, hence special solder alloys or board

materials may be required to maintain the reliability of the assembly.

•

These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift increasing over

operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime.
