Understand The Color Code Of A Capacitor
Consider the capacitor below, it is a ceramic disc type that has the code 473J labeled on its body. So, the 4 is the 1 st digit, 7 is the 2 nd digit, and the 3 is the multiplier in pico-Farads, pF, and the letter J is the tolerance. This can be translated to 47pF * 1,000 (3 zero''s) = 47,000 pF or 0.047uF and the J represents tolerance of +/- 5%.
