These are Carbon Film Resistor with a value of 270 ohm 1/2W and tolerance of ±5%

18 ohm 5% 1/4 Watt Resistor (Box of 5000) - CFR 5K6 It can be used eitherThese are Carbon Film Resistor with a value of 18 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 Brown, Grey, Black, Gold for these 18E resistors, make it easy to identify the value of these resistors. Specification Resistance Value 18 ohm Color Code
