resistornätverk
A resistornätverk, or resistor network, is an electronic component consisting of a set of resistors connected in a fixed configuration to provide precise, stable voltage or current references, division ratios, or filtering functions. The network is typically manufactured as a small metal-foil or metal-oxide chip, a soldered to a substrate, or mounted on flexible board material. Because all the resistors inside the network are fabricated or welded together during the manufacturing process, tolerances, temperature coefficients, and cross‑talk between elements are tighter than if the resistors were assembled individually. This makes resistor networks commonly used in precision instrumentation, active filters, and calibration references.
Resistor networks come in several standard formats. The most common form is the surface‑mount 0.1‑inch array,
Applications of resistornätverk include localised voltage dividers for PCB reference rails, input biasing networks for op‑amps,
