Resistor Terms:



'A', 'B/C', 'D/E', 'F-M', 'N', 'P', 'R', 'S', 'T', 'V'

Tapped Resistor: A wire-wound, fixed resistor having one or more additional terminals along its length, generally for voltage-divider applications. Potentiometer Manufacturers

TCR: Temperature Coefficient of Resistance. TCR causes the value of the resistance to vary with change in temperature.

Temperature Coefficient: The magnitude of change in resistance due to temperature, usually expressed in percent per degree Celsius or parts per million per degree Celsius (ppm/C).

Thermistor: A resistor whose resistance varies with temperature in a defined manner. A device which produces a large change in resistance due to a change in body temperature. There are two types of Thermistors: PTC and NTC. Companies that Manufacturer Thermistors, Thermistor Derating Graph

Tolerance: A permissible deviation from a specified value. A maximum electrical or mechanical variation of specifications that can be tolerated without impairing the operation of a device. Definition of Resistor Tolerance

Trimmer: A variable resistor. Designed for less then frequent changes [occasional]~ a trim pot on a PCB to finalize a circuit resistance.
