Appendix B:
Reading Component Values
Capacitors
Capacitors’ values are usually stamped on the capacitor. However, not all
capacitors are labeled the same way. For example, a 0.022 microfarad
(µF) capacitor may be marked as .022 K, 22n, .022 µF, or 223 K. The last
example could be read 22 x 10
3 picofarads (pF), where 1 pF=10 6 µF.

1% tolerance resistors are recommended.
Resistors with 5% or 10% tolerance have two (instead of three) significant figures.
The third band is the multiplier and the fourth is the tolerance.
