Chip resistors are devices manufactured in square or rectangular chip packages. Resistors. are components that oppose the flow of electrical current. They can be used to protect, operate, or control circuits.
Chip capacitors are simply capacitors manufactured as integrated circuit (IC) devices, Chip capacitors typically do not have leads and mount directly onto a printed circuit board (PCB), and are therefore considered surface mount (SMT) products.
An electrolytic capacitor is a polarized capacitor which uses an electrolyte to achieve a larger capacitance than other capacitor types.
