Composition Resistor
Carbon Composition Resistors have been used for well over 100 years. Today, applications for Carbon Composition Resistors include power supplies and welding controls. These parts consist of a solid cylindrical resistive element (made of a carbon composition) with embedded wire leads or metal end caps to which the lead wires are attached. The body of the resistor is protected with paint or plastic, and color rings are painted onto the body to indicate the resistance value (in Ohms). Specific attributes which are important in selecting the right Carbon Composition Resistor for your application include: Package Type – usually Axial; Maximum Voltage Rating (V); Power Rating (W); Resistance (Ω); Tolerance (%); Operating Temperature Range (⁰C); Temperature Coefficient (ppm/⁰C); and the part’s Dimensions (mm) – usually length and diameter for these parts. Our offering of Carbon Composition Resistors feature a range of resistance from 0.01 Ω to 15 MΩ. The Power Rating varies from 0.25W to 1.0W.
