Ceramic Resistor Identification

Example of a wire wound resistor construction.

Ceramic resistor identification.

For example a resistor with brown green and green bands is rated at 15 mega ohms 15 000 000 ohms. Browse our computer products electronic components electronic kits projects and more. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.

Then by just using numbers and letters as codes.
