What is electronic components？

Electronic components are fundamental elements in electronic circuits, typically packaged individually and with at least two or more leads or metal contacts. These components need to be interconnected to form electronic circuits with specific functions, which can be individual packages or more complex components. Electronic components may be active, meaning they can generate current or signals themselves, or they may be passive, only serving to transmit current or signals. In order to ensure the normal operation and service life of electronic components, they are often packaged with synthetic resin to improve insulation and environmental protection capabilities.

Electronic components include: resistors, capacitors, inductors, potentiometers, electronic tubes, heat sinks, electromechanical components, connectors, semiconductor discrete devices, electroacoustic devices, laser devices, electronic display devices, optoelectronic devices, sensors, power supplies, switches, micro motors, electronic transformers, relays, printed circuit boards, integrated circuits, various circuits, piezoelectric, crystal, quartz, ceramic magnetic materials Printed circuit substrates, electronic functional process specific materials, electronic adhesive (tape) products, electronic chemical materials and components, etc.

What is active components in electronics?

Active components refer to components that can provide energy in a circuit, such as power sources, inductors, capacitors, etc., and have the ability to store and release electrical energy. These types of components rely on external power sources during operation, or have internal power sources present. Common active components include electronic tubes, transistors, integrated circuits, etc., which are mainly used for signal amplification, conversion, and other functions. Active components are relative to passive components, which do not rely on external power sources or have no internal power supply during operation. Active components can be divided into two categories based on their roles in the circuit: independent sources and controlled sources. Independent sources such as voltage sources and current sources can cause changes in the current or voltage of other components in the circuit. However, the controlled source does not have an excitation effect in the circuit, and its current and voltage states are affected by other components.

What is passive components in electronics?

Passive components refer to electronic components that can operate in electronic circuits without the need for external power sources. They mainly achieve their functions by consuming their own electrical energy, rather than simultaneously consuming and supplying electrical energy like active components. Passive components include resistors, capacitors, and inductors, which play a role in distribution, regulation, and filtering in circuits. Resistors are used to control the magnitude of current and regulate voltage, capacitors are used to store charges, and inductors are used to store magnetic fields and can change the phase of current. The characteristic of these components is that they can function normally without an independent power supply in the circuit.

The difference between active electronic components and passive electronic components

Electronic components that require power are called active electronic components, while electronic components that do not require power are called passive electronic components. Active electronic components are generally used for signal amplification, transformation, etc., while passive electronic components are used for signal transmission or directional signal amplification.

The characteristics of passive electronic components are that if there is no form of power supply inside the electronic components when they are working, they are called passive electronic components.

Passive electronic components have two basic characteristics

1. Consume or convert electrical energy into different forms of energy.

2. Just input the signal and it can work normally without the need for an external power source.

The characteristics of active electronic components are called active electronic components if there is a power supply inside the electronic components when they are working.

Active electronic components have two basic characteristics

1. It also consumes electricity on its own.

2. In addition to the input signal, an external power supply is also required to function properly.

Where to buy electronic components?

There are many ways to purchase electronic components, and the following are some common ways:

1. Electronic component market: You can purchase electronic components from the local electronic component market. These markets typically offer various models and brands of electronic components at relatively affordable prices.

2. Online Electronic Component Mall: Many large e-commerce platforms now offer sales services for electronic components. For example, on platforms such as Digikey, Mouser, Arrow, LCSC, you can browse various models and brands, and view reviews and suggestions from other buyers. This shopping method is usually more convenient and fast, but attention needs to be paid to the quality and authenticity of the goods.

3. Professional electronic component suppliers: If you need higher quality and lower price electronic components, you can choose to purchase from professional electronic component suppliers. They usually have a wider range of inventory and more professional technical support to meet your special needs.

4. Official website of electronic component manufacturers: Some electronic component manufacturers will provide product catalogs and FAQs on their official website. Through this method, you can directly contact the manufacturer to obtain the latest product and support information.
