390 ohm 5% 2 Watt Resistor (Box of 1000) - MOF RS-485 and RS422 communication These are Metal Film Resistor

These are Metal Film Resistor with a value of 15 ohm 2W and tolerance of ±5%

Brown for these 68E resistors

you can refer to A7800 Datasheet

The AP1682 eliminates the optocoupler and secondary control circuitry while also providing accurate constant current (CC) regulation

390 ohm 5% 2 Watt Resistor (Box of 1000) - MOF RS-485 and RS422 communication These are Metal Film ResistorThese are Metal Film Resistor with a value of 390 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 Orange, White, Black, Gold for these 390E resistors, make it easy to identify the value of these resistors. Specification Resistance Value 390 ohm Color Code
