Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity. Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment. Practical resistors as discrete components ...
Vishay Intertechnology, Inc. is an American manufacturer of discrete semiconductors and passive electronic components founded by Polish-born businessman Felix Zandman.Vishay has manufacturing plants in Israel, Asia, Europe, and the Americas where it produces rectifiers, diodes, MOSFETs, optoelectronics, selected integrated circuits, resistors, capacitors, and inductors.
High value resistors (HVR) are electronic components used for special applications, such as in bio-medical systems, measurement equipment and some condenser microphones. While discrete resistors in the range of few tens of megohm are very common, making giga-ohm range resistors is more complicated. Discrete resistors are available up to several ...
Various resistor types of different shapes and sizes. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
For V GS levels near 0 V, the triode linear range extends from about −0.2 V to 0.2 V. As the value of V GS is increased, the linear triode region is significantly reduced. Conversely, when linearization resistors are used, a similar IV curve swept simulation indicates that the linear triode region is significantly extended.
SMD resistors on the backside of a PCB. Pass current in proportion to voltage and oppose current. Resistor – fixed value Power resistor – larger to safely dissipate heat generated; SIP or DIP resistor network – array of resistors in one package; Variable resistor Rheostat – two-terminal variable resistor (often for high power)
