There are many kinds of capacitors and several popular ones are pictured here. Generally, capacitors have two leads. Some are axial leaded, like resistors, and others are radial leaded, with both leads at one end. Stompbox layouts seem to use radial leaded capacitors most often, but axial leaded are just as good. Unlike resistors, some capacitors are polarized, with positive and negative leads: the voltage across such capacitors must agree with the polarity of the leads. Take care to orient polarized capacitors correctly in a circuit.
