ResistorArray

A ResistorArray is an electronic component containing multiple resistors integrated into a single package. This integration offers several advantages over discrete resistors, including reduced board space, simplified assembly, and improved performance due to matched resistor values. Resistor arrays are commonly found in applications where multiple resistors with precise ratios or identical values are required, such as digital-to-analog converters, current sensing, and pull-up/pull-down networks for digital logic.

There are two primary types of resistor arrays: isolated and bussed. In an isolated resistor array, each resistor element has its own separate terminals, functioning independently. A bussed resistor array, also known as a common resistor array, shares a common terminal for multiple resistors, simplifying connections in certain circuit designs. The resistors within an array are typically manufactured using thin-film or thick-film technology, similar to discrete resistors, and can be fabricated with various resistance values, tolerances, and power ratings. The packaging for resistor arrays varies, with common form factors including dual in-line packages (DIP), small outline packages (SOP), and quad flat no-lead (QFN) packages, designed for surface-mount or through-hole assembly.
