Precision Thin Film Chip Resistor Array

ACAC 0612 (concave terminations) and ACAS 0612 (convex

terminations) thin chip resistor arrays combine the proven

reliability of precision thin film chip resistor products 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

• Advanced thin film technology

• Two pairs or four equal resistor values

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

• Tolerance matching down to 0.1 % (± 0.05 %)

• Pure Sn termination on Ni barrier layer

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.
