Resistors

Resistors complement ‘active’ components like op-amps, micro-controllers, or integrated circuits for a variety of operations like biasing, filtering, and pulling up I/O lines. Variable resistors can be used to change the properties of a circuit. Current-sensing resistors are used to measure the current in a circuit. The unit of resistance is the ohm (Ω).

TYPES There are several different types of resistors, which differ by power rating, size, performance, and cost. Below are some common resistor types: chip SMD resistors, through-hole resistors, wire-wound resistors, current sense resistors, thermistors, and potentiometers. We've also included their characteristics, applications, package information, as well as info on part selection.
