Classification of commonly used electronic components:
Active and passive components.
Active components refer to components that, when supplied with energy, can amplify, oscillate, control current or energy distribution and other active functions of electrical signals, and even perform data operations and processing. Active components include various transistors, integrated circuits, picture tubes and displays.
Compared to active components, passive components mean they cannot excite, amplify, oscillate, etc. electronic signals. They respond passively and submissively to electrical signals. Electrical signals pass through electronic components based on their original basic characteristics. The most common resistors, capacitors, inductors, etc. are passive components.
Active and passive components.
Active ingredient corresponds to the active ingredient. If an electronic component has an internal power supply when operating, the device is called an active device and requires energy to perform its specific functions. Active devices themselves also consume power, and high-power active devices are usually equipped with heat sinks.
Corresponding to passive components are passive components. When signals pass through resistors, capacitors and inductors in the circuit, they can complete the specified functions and do not require an external excitation power supply, so they are called passive devices. Passive devices consume very little electrical energy themselves or convert electrical energy into different forms of other energy.
Discrete components and integrated circuits.
From the aspects of physical structure, circuit function and engineering parameters, active devices can be divided into two categories: discrete components and integrated circuits. Discrete components versus integrated circuits.
Integrated circuit (IC, integrated circuit) is a kind of transistor, resistor, capacitor, inductor and other components and wiring required in a circuit, and is made on a small or several small semiconductor chips or dielectric substrates. And packaged into a whole, electronic components with circuit functions.
Discrete components refer to individual electronic components such as ordinary resistors, capacitors and transistors, collectively referred to as discrete components. A discrete component is the “minimum” component that has a single function and has no functional units of other components inside it.
Distinguish between circuit components and connecting components.
Passive devices in electronic systems can be divided into circuit devices and connection devices according to the circuit functions they perform.
