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 ...

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 ...

Open element

Electronic components; Resistors

A component or adjustable resistor which has its resistive element exposed. An open-element resistor supported by a frame but not totally surrounded by an enclosure. The graphic to the right shows an ...

Stand-off resistor

Electronic components; Resistors

A resistor mounting method that rises a high-power through hole resistor off the printed wiring board (PWB) surface so that the resistor does not impart its heat onto the board laminate. Parts which ...

Chip attenuator

Electronic components; Resistors

A Surface mount device that provide either 'Pi' attenuator pads, or 'T' attenuator pads, (PI-Pads, T-Pads). PI-Pads have a minimum of four leads, two for the common lead (ground) and one each for the ...

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 ...

Taper

Electronic components; Resistors

References how a potentiometer changes value as the wiper is moved across its resistive element. There are two general types of taper used with potentiometers: a linear taper and an audio taper. The ...
