Chassis Mount Resistors
Chassis mount resistors are passive components that oppose the flow of current and are used to adjust signal levels, divide voltages, bias active elements, or terminate transmission lines among other uses. These resistors are typically larger and may dissipate up to 2500 watts of heat energy. They are mounted using housing flanges, screws, braces, or brackets.
Chip Resistor - Surface Mount
Resistors provide opposition to current flow, in a manner that is proportional to the electric potential (voltage) imposed across them, and which is ideally unaffected by signal frequency or changes in temperature. Resistors described as surface mount chip types are designed to be affixed to the surface of a printed circuit board and incorporate a single resistor per device package.
Resistor Networks, Arrays
Resistor networks or arrays are devices of two or more resistors in a single surface mount or through-hole package. The resistors may be isolated from each other or connected in an R2R ladder (digital to analog converter), bussed, voltage divider, dual terminator, digital-to-analog converter, or decade resistor circuit type. Single or multiple resistance values range from zero (jumper) to 5 GΩ and 0.1% to 15% tolerance.
Products in the specialized resistor family are adapted for particular purposes and often have uncommon form factors as a result. Examples include resistors designed to fit across the leads of large electrolytic resistors for safety discharge purposes, liquid-cooled resistors, and low resistance shunts for use in relatively high current applications such as automotive electrical systems.
Through Hole Resistors
Through-Hole Resistors are devices which oppose the flow of current. They have two wire terminals which are designed to be inserted and soldered to a printed circuit board (PCB) or are used in a breadboard. The characteristics are resistance (0 ohms to 500 G ohms), tolerance (jumper, ±0.001% to ±5%), power (watts), and composition (carbon composition, carbon film, ceramic, metal element, metal film, metal foil, metal oxide film, thick film, thin film, or wirewound).
