Capacitors typically look like this. We have an electrolytic and a ceramic type capacitor. The electrolytic is polarised meaning one side must be connected to the positive and one to the negative of the power supply. The ceramic type can generally be connected either way. On the side of the electrolytic capacitor, we.

Depending on what you are trying to accomplish, the amount and type of capacitance can vary. The first objective in selecting input capacitors is to reduce the ripple voltage amplitude seen at the input of the module.
