3.9 ohm 5% 1 Watt Resistor (Box of 1000) - MOF 15E These are Carbon Film ResistorThese are Metal Film Resistor with a value of 3. 9 ohm 1W 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 Orange, White, Gold, Gold for these 3. 9E resistors, make it easy to identify the value of these resistors. Specification Resistance Value 3. 9 ohm Color
