51k ohm 5% 1/4 Watt Resistor (Box of 5000) - CFRThese are Carbon Film Resistor with a value of 51k ohm 1 4W and tolerance of 5%. These Axial resistors are cylindrical in shape with copper plated steel leads extending from each end. Carbon Film Resistor limit the flow of electric current using a Carbon Film. The printed colour code rings, which are Green, Brown, Orange, Gold for these 51K resistors, make it easy to identify the value of these resistors. Specification Resistance Value 51k ohm Color
