(2) In applications with defined resistance ratios like voltage dividers or feedback circuits, an array with a defined tracking of e.g. 10 ppm/K is 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 %.

The rated dissipation applies only if the permitted film temperature is not exceeded. These resistors do not feature a limited lifetime when operated within the permissible limits.
