180k ohm 5% 2 Watt Resistor (Box of 1000) - MOF bridge rectifier A power LED indicates thatThese are Metal Film Resistor with a value of 180k ohm 2W and tolerance of 5%. These Axial resistors are cylindrical in shape with copper plated steel leads extending from each end. Metal Film Resistor limit the flow of electric current using a Metal Film. The printed colour code rings, which are Brown, Grey, Yellow, Gold for these 180K resistors, make it easy to identify the value of these resistors. Specification Resistance Value 180k ohm Color Code
