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 %)
• RoHS compliant component, compatible with lead (Pb)-free
and lead containing soldering processes
APPLICATIONS
• Precision analogue circuits
• Voltage divider
• Feedback circuits
• Signal conditioning

Notes
(1) Resistance values to be selected from E24, E48 and E96
(2) The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat-flow support of the printed
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.
