The code values help in identifying the capacitance value of a capacitor without having to write the full value in Farads. Q: How are capacitor code values expressed?
How do you read a large capacitor?
To read a large capacitor, first find the capacitance value, which will be a number or a number range most commonly followed by µF, M, or FD. Then look for a tolerance value, typically listed as a percentage. Next, check the voltage rating, which is usually listed as a number followed by the letters V, VDC, VDCW, or WV.
How do you know if a capacitor is a digit?
Digit-Character-Digit. Some small capacitors are marked with codes like 1n0. The digits are the values before and after the decimal point and the the character tells you the dimension; so the example given is 1.0 nF (nano-Farad). Look for a letter code. Some capacitors are defined by a three number code followed by a letter.
