A resistor whose ohmic value cannot be adjusted or varied. The resistance element consists of either a thin layer of conductive material, containing either binders or insulating materials, deposited on an insulated form; or an alloy of metal and ceramic materials, usually fused to an insulated form. Opposition to the flow of current is an inherent property of the materials used and is manifest by the heat dissipation in the resistor. See also attenuator, fixed and resistor, fixed, composition. Excludes:carbon composition type resistors.
