Resistors and potentiometers are passive electronic components that oppose the flow of either alternating current (AC) or direct current (DC).
Resistors and Potentiometers Categories

Chip Resistors (231 suppliers)

Chip resistors are passive resistors with a form factor of an integrated circuit (IC) chip. Typically, they are manufactured using thin-film technology.

Current Sensing Resistors (73 suppliers)

Current sensing resistors convert the current flowing through it to a voltage drop. Monitoring or measuring this voltage drop allows the current through the resistor to be measured. Applications for current sensing resistors include power supplies, receptacles, and battery packs. 

Digital Potentiometers (49 suppliers)

Digital potentiometers are three-terminal resistors with an adjustable center connection. To set the output resistance, a digital signal is sent through an electrical interface.

Dynamic Braking Resistors (DBRs) (29 suppliers)

Dynamic braking resistors (DBRs) produce braking torque and absorb the high amounts of energy generated by stopping electric motors. They are used in variable-speed drive systems such as elevators, cranes, and trains. 

Electronic Loads and Load Banks (109 suppliers)

Electronic loads and load banks are used to test electrical and electronic equipment. They mimic load requirements for testing and troubleshooting purposes.

Potentiometers, Rheostats, and Trimmers (342 suppliers)

Potentiometers, rheostats and trimmers are three-terminal resistors that are used to measure or divide voltages, and to protect or control circuits.

Power Resistors (114 suppliers)

Power resistors are used in power generation and distribution, high-voltage applications, control systems, and other power system applications. They include load banks, grounding resistors, and dynamic braking resistors.

Resistor, Capacitor Networks (127 suppliers)

Resistor, capacitor networks (RC networks) are integrated circuits (ICs) that contain resistor-capacitor arrays in a single chip.

Resistors (744 suppliers)

Resistors are electrical components that oppose the flow of either direct or alternating current. They are used to protect, operate, or control circuits.

Shunt Resistors (86 suppliers)

Shunts resistors are connected in parallel with an instrument or component to divert electrical current. They provide an alternate path for current in case of failure.

Varistors (175 suppliers)

Varistors are voltage-clamping devices that can absorb current without damage. They are typically used in surge protection devices.

Wirewound Resistors (82 suppliers)

Wirewound resistors are power resistors made by winding a metal wire around a core.
