56 ohm 5% 1/4 Watt Resistor (Box of 5000) - CFR 8-Bit CMOS Microcontrollers The LED is optically coupled

The LED is optically coupled to an integrated high-gain photodetector

1mm DC jack

It is with connectors for corrosion resistance ensuring consistent and reliable conductivity

Gold for these 150K resistors

Brown for these 68K resistors

56 ohm 5% 1/4 Watt Resistor (Box of 5000) - CFR 8-Bit CMOS Microcontrollers The LED is optically coupledThese are Carbon Film Resistor with a value of 56 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 Green, Blue, Black, Gold for these 56E resistors, make it easy to identify the value of these resistors. Specification Resistance Value 56 ohm Color Code
