Resistor 4R7 5% 1/4watt

Description Resistor 4R7 5% 1/4watt Resistor 4R7 5% 1/4watt Working with breadboards or need easy to use through-hole components Then these resistors are for you! Available in a wide range of values. They are constructed out of a ceramic carrier with a thin pure carbon film around it, that functions as resistive material. Resistors are electronic components which have a specific, never-changing electrical resistance. The resistors resistance limits the flow of electrons through a circuit. They are passive components, meaning they only consume power (and cant generate it). Resistors are usually added to circuits where they complement active components like op-amps, microcontrollers, and other integrated circuits. Commonly resistors are used to limit current, divide voltages, and pull-up I/O lines The carbon film resistors whose ceramic core has a high alumina content offering power to size ratios not normally associated with carbon film products. A low-cost solution, combined with high reliability, makes the CFR series of components suitable for use in most types of circuits, including audio, communications, measurement and computer applications. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. High-power resistors that can dissipate many watts of electrical power as heat may be used as part of motor controls, in power distribution systems, or as test loads for generators. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity. Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment. Practical resistors as discrete components can be composed of various compounds and forms. Resistors are also implemented within integrated circuits.
