7.5k ohm 5% 1/8 Watt Resistor (Box of 5000) - CFR 430E These are Metal Film ResistorThese are Carbon Film Resistor with a value of 7. 5k ohm 1 8W 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 Violet, Green, Red, Gold for these 7K5 resistors, make it easy to identify the value of these resistors. Specification Resistance Value 7. 5k ohm Color
