Introduction to common sense of electronic components

Electronic components are components of electronic components and small electric machines and instruments. They are often composed of several parts and can be used in similar products. They often refer to certain parts in electrical appliances, radios, meters and other industries, such as capacitors and transistors. The general term for sub-devices such as hairspring, spring, and spring, and diodes are common ones.

In layman's terms, the basic parts used to manufacture or assemble electronic complete machines can be called components, which are independent individuals in electronic circuits.

Active components and passive components

Active components refer to components that can stimulate and amplify electrical signals, oscillate, control current or energy distribution and other active functions and even perform data operations and processing when energy is supplied.

Active components include various transistors, integrated circuits, image tubes and displays.

Relative to active components, passive components mean that they cannot stimulate, amplify, oscillate, etc., and respond to electrical signals passively, while electrical signals pass through electronic components according to their original basic characteristics.

The most common resistors, capacitors, inductors, etc. are passive components.

Active components and passive components

Active components correspond to active components. If there is a power supply inside the electronic component when it is working, then this kind of device is called an active device, and it needs a source of energy to achieve its specific function.

Active devices themselves consume power, and high-power active devices usually have a heat sink.

Corresponding to passive components are passive components. Resistor, capacitance and inductance components can complete the specified functions with signals passing through the circuit, without external excitation power, so they are called passive devices.

The passive device itself consumes very little electric energy, or converts electric energy into other forms of energy.

Discrete components and integrated circuits

From the physical structure, circuit function and engineering parameters, active devices can be divided into two categories: discrete devices and integrated circuits. Discrete components are relative to integrated circuits.

An integrated circuit (ic integrated circuit) is a kind of interconnection of transistors, resistance-capacitance and other components and wiring required in a type of circuit, fabricated on a small or several small semiconductor wafers or dielectric substrates, and packaged into one Overall, 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. Discrete components are single-function, "minimum" components, and there are no other functional units inside.

Distinguish between circuit components and connection components

Passive devices in electronic systems can be often divided into circuit-type devices and connection-type devices according to the circuit functions they perform.
