Overview
Electronic components are devices used to build circuits.
NOTE: This page should likely be updated to better include lists of components, probably catagorized in a similar manner to this wikipedia page.

Capacitors
Types of Capacitors
Electrolytic capacitors are polarised but ceramic caps are not.
Reading Capacitors
Most capacitors have number codes if the capacitor is too small to have the full value written on it. It is usually a three number code where the last number is the multiplier similar to resistors. The base numbers are in pF (picoFarad).
For example, the label "332" is 33*10^{2} = 3300 pF = 3.3 nF
Diodes
Light Emitting Diodes
Schottky diode
Zener Diodes
Integrated Circuits
Resistors
Standard resistor
Potentiometers
Pots also have 3 number codes with the third being a multiplier. The base value is in Ohms.
For example, the label "103" is 10*10^{3} = 10 kilo Ohms
