An electronic component that is used to vary the amount of current that flows through a circuit. It works by sliding a wiper terminal across a resistive material, typically a thin film or chunk of ...

Designers of instruments or control systems often find that component performance limits overall equipment performance in areas such as stability, frequency response, noise, and ESD. This is ...

Vishay Intertechnology, Inc. (NYSE: VSH) introduced a new AEC-Q200 qualified, high-power thick film resistor engineered to ...

Variable resistors have many practical applications including volume controls, eg on a radio, and speed controls, eg on a mixer or a drill. There is usually a dial or sliding switch on the variable ...

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

You can use a photoelectric FET as a variable resistor or a potentiometer in combination with a fixed resistor. The H11F3M photoelectric FET has an isolation voltage of 7.5 kV, enabling you to safely ...

The Toshiba TC78H670FTG two-phase, bipolar, stepper-motor driver removes the need for any external current-sense resistor by incorporating on-chip current detection. It’s often desirable or even ...

I need an adjustable power resistor that can be switched with a resolution of 1Ω. After some thought and web surfing, I bought some 10W wirewounds, which are available in E24 values so that 1, 3, 12 ...
