Resistors control the electric currents that pass through them, as well as the voltage in each component connected to them. Without resistors, other components may not be able to handle the voltage and this may result in overloading.
2. Transistors
Transistors are crucial to the printed circuit board assembly process due to their multi-functional nature. They are semiconductor devices that can both conduct and insulate and can act as switches and amplifiers. They are smaller in size, have a relatively longer life, and can operate at lower voltage supplies safely without a filament current. Transistors come in two types: bipolar junction transistor (BJT) and field effect transistors (FET).
3. Capacitors
Capacitors are passive two-terminal electronic components. They act like rechargeable batteries – they can store electrical energy, and then transmit that energy again when needed.
4. Inductors
Inductors are passive two-terminal electronic components that store energy in a magnetic field when an electric current passes through them. Inductors are used to block alternating currents while allowing direct currents to pass. They can be combined with capacitors to make tuned circuits, which are used in radio and TV receivers.
5. Diodes
Diodes are semiconductor components that act as one-way switches for currents. They allow currents to pass easily in one direction but restricts currents from flowing in the opposite direction.
