capacitor

120uF 50V  Electrolytic Capacitor is a high quality electrolytic capacitor which offers long life and high reliability. Electrolytic Capacitors are most commonly used type of capacitors in Electronic Circuits.

This is a 150pF Ceramic Capacitor  Use this capacitor for power decoupling, having a smooth power in your circuit, timing circuits etc. It is always a good idea to put one of these next to the power pins of a microcontroller.
