Resistor 12R471 Carbon Film Resistor 470 Ohms 1/4W 5% Axial Through Hole
Carbon film resistors are a fixed form type resistor. They are constructed out of a ceramic carrier with a thin pure carbon film around it, that functions as resistive material.
Basic structure of this type of resistor is constructed by means of film deposition technique of deposition a thick film of resistible material such as pure carbon or metal on to an insulating core. The desired value of resistance of metal film resistor or carbon film resistor can easily be obtained by either trimming the layer of thickness or by cutting helical grooves of suitable pitch along its length. That means for different resistance values, the length and depth of the helical grooves is maintained accordingly.
