In manufacturing carbon film resistors, a carbon film is deposited on an insulating substrate, and a [[helix]] is cut in it to create a long, narrow resistive path. Varying shapes, coupled with the [[resistivity]] of [[amorphous]] carbon (ranging from 500 to 800&nbsp;μΩ&nbsp;m), can provide a wide range of resistance values. Carbon film resistors feature lower noise compared to carbon composition resistors because of the precise distribution of the pure graphite without binding.<ref>{{cite web|title=Carbon Film Resistor|url=http://www.resistorguide.com/carbon-film-resistor/|work= The Resistorguide|access-date=10 March 2013}}</ref> Carbon film resistors feature a power rating range of 0.125&nbsp;W to 5&nbsp;W at 70&nbsp;°C. Resistances available range from 1&nbsp;ohm to 10&nbsp;megaohm. The carbon film resistor has an [[operating temperature]] range of −55&nbsp;°C to 155&nbsp;°C. It has 200 to 600 volts maximum working voltage range. Special carbon film resistors are used in applications requiring high pulse stability.<ref name=Vishay08/>
