Passive Discrete - Capacitors

Back to basics (covered in Deciphering Schematics):

Resistors, capacitors, and inductors are primary types of passive discrete components. In their most basic form, they come with two-terminals, through-hole or SMD. The chart below shows the types of resistors:

Capacitors has the ability to store electrical charge exponentially, the amount of charge being determined by the capacitance value and the voltage applied across the device (i.e., Q = CV). One important use of capacitors is passing alternating current while blocking direct current, also known as ‘AC coupling’.
