Classification of electronic components

The basic parts used to manufacture or assemble the whole electronic machine are called electronic components, which are independent entities in the electronic circuit.

1. Active components and passive components

Active components refer to components that can perform active functions such as excitation amplification, oscillation, current control or energy distribution of electrical signals, and even perform data operations and processing when energy is supplied.

Active devices include a wide variety of transistors, integrated circuits (ics), picture tubes, and displays.

Passive components, as opposed to active components, mean that they cannot be excited, amplified, oscillated, etc. By electrical signals, and that the response to electrical signals is passive and obedient, while electrical signals pass through electronic components according to their original basic characteristics.

The most common resistor, capacitors, inductor, etc. Are passive components. Active and passive components

Active components correspond to active components. If there is a power source inside the electronic component when it works, the device is called an active device, which needs a source of energy to achieve its specific function.

Active devices themselves also consume electrical energy, and high power active devices usually have heat sinks.

Corresponding to passive elements are passive elements. Resistors, capacitors and inductors are called passive devices because they can complete the specified function when the signal passes through the circuit without external excitation power supply.

Passive devices consume little electrical energy by themselves or convert electrical energy into other energy in different forms.

2. Discrete components and integrated circuit IC

Active devices can be divided into discrete devices and integrated circuits in terms of physical structure, circuit function and engineering parameters. Discrete components are the opposite of integrated circuits (IC).

Integrated circuit (IC integrated circuit) is a kind of electronic components with circuit function, which interconnects transistors, resistors, capacitors, inductors and other components and wiring required by a class of circuits, and is manufactured on a small or several small semiconductor chips or dielectric substrates, packaged as a whole.

Discrete components refer to ordinary resistors, capacitors, transistors and other single electronic components, collectively referred to as discrete components. A discrete component is a single, "minimal" component with no other component functional units inside.

3. Distinction between circuit components and connection components

Passive devices in electronic systems can be divided into circuit devices and connection devices according to their circuit functions.
