Step 7: Other Small Capacitors And Quartz Crystal
Install other small capacitors. You can identify them by labels listed on the picture.
Also, it's good to know that there are two types of notation for a capacitor value.
Style 1: 3-digit. The first two digits should be read as they are, and then you need to
add as much zeroes as are indicated by the third digit, and interpret this as the value in
pF. 150 means 15 pF, 334 means 330000 pF (= 330 nF). Very simple.
Style 2: The value usually consists of 2 or 3 digits and a letter p, n or u (µ) indicating
the unit of the value. This letter actually stands in place of the decimal point, so 33n
means 33 nF, 3n3 means 3.3 nF, and n33 means 0.33 nF (= 330 pF). The following
“J100” on film capacitors indicates the tolerance class, and the voltage rating.
