224 47µF

Ceramic disc capacitor

Example 1: What is the capacitance value of these capacitors that marked
a. 22 => 22 picofarad
b. 330 => 330 picofarad
c. 471 => 47x10 = 470 picofarad
d. 562 => 56x10² = 5600 picofarad or 5.6 nanofarad
e. 103 => 10x10³ = 10000 picofarad or 10 nanofarad
4
f. 224 => 22x10 = 220000 picofarad or 220 nanofarad or .22
microfarad
5
g. 335 => 33x10 = 3300000 picofarad or 3300 nanofarad or 3.3
microfarad
