Resistors

current sense resistor

Electronic components; Resistors

Ultra low ohm devices used to measure current. Current sense resistors are low resistance precision resistors used to measure AC or DC electrical currents by the voltage drop those currents create ...

power rating curve

Electronic components; Resistors

A curve that indicates the percentage of nominal wattage to be applied at a temperature other than that specified as maximum power dissipation. A power rating curve may also be called a derating ...

noise

Electronic components; Resistors

An unwanted voltage fluctuation generated within the resistor. Noise is any any spurious variation in the electrical output not present in the input. Total noise of a resistor always includes Johnson ...

thermal shock

Electronic components; Resistors

A sudden change in temperature. Thermal shock test; The resistors shall then be mounted on a rack of low-heat conducting material, and rated power shall be applied until thermal stability has been ...

carbon composition resistor

Electronic components; Resistors

A resistor that uses a slug of finely ground carbon with a mixture of silica to form the resistive element. Leads are attached to both ends of the slug which is than covered by some molded covering, ...

resistance noise

Electronic components; Resistors

Thermal noise caused by the increase of current in a resistor due a thermal increase in the device.

bleeder resistor

Electronic components; Resistors

A resistor connected across a power pack or other voltage source to improve voltage regulation by drawing a fixed current value continuously. It is also used to dissipate the charge remaining in ...
