What Are Resistor networks, arrays？

Resistor networks, also known as arrays, consist of two or more resistors housed in a single surface mount or through-hole package. These resistors can be either isolated from one another or configured in various types, such as an R2R ladder (for digital-to-analog conversion), bussed, voltage divider, dual terminator, digital-to-analog converter, or decade resistor circuit. They can feature single or multiple resistance values, ranging from zero (jumper) to 5 GΩ, with tolerances from 0.1% to 15%.

The Structure of Resistor Arrays

A resistor array usually comprises multiple individual resistors arranged in a specific configuration. The most common arrangements are series, parallel, and combination circuits, each providing distinct electrical characteristics for various applications.

Series Configuration: In this setup, resistors are connected end-to-end, and the total resistance is simply the sum of all individual resistances.

Parallel Configuration: Here, resistors connect at both ends of their terminals, resulting in a total resistance that is less than the smallest resistor in the array.

Combination Configuration: This type includes both series and parallel arrangements, and the total resistance is calculated using specific rules based on the resistor combinations.
