PATTERN STYLES FOR CHIP RESISTOR ARRAYS

Note

(1)

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 ± 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 %.
