Identify Electronic Components (Quick Reference)

There are many versions of the symbol for each component in electronics. Below I’ve listed the ones I’m using the most.

Battery

Resistor

Capacitor (Polarized)

Capacitor (Non-Polarized)

Light-Emitting Diode (LED)

Transistor

Integrated Circuit

The symbol for intergrated circuits (IC) come in different forms. An IC that has a common function like a logic gate or an op-amp, usually is shown as the symbol for that function (like the schmitt-triggered inverter below). An IC that does not have a symbol for it’s function is usually shown as a box with pins and pin names (like the 555 timer below).
