A bipolar junction transistor (BJT) is a current-driven semiconductor element that uses a small amount of current to control the flow of a larger electric current. In contrast to a unipolar transistors, such as a field-effect transistors which uses only one kind of charge carrier, a BJT uses both electrons and electron holes as charge carriers. BJT Transistors can be used to amplify weak electrical signals and are also used as oscillators or as switches.

Electricity is an important driving force for economic and social development and plays a vital role in the national economy. The equipment used in the electric supply industry is essential for maintaining the stable and reliable operation of the power system.

Governments are actively promoting the development of regional semiconductor supply chains. AI combines emerging technologies and applications such as the Internet of Things, automotive electronics, and compound semiconductors to drive the growth momentum of the semiconductor industry.

In the next 10 years, the global auto industry will face the most significant change in history, with electric vehicles replacing internal combustion engine vehicles.

The global chip shortage, now dragging into its second year, has shaken the electronics industry to its core, crimping the world's ability to build everything from cars to consumer goods and raising prices, and there are a lot of variables complicating the recovery.

Even if the epidemic slows down, video conferencing will have the opportunity to become the new normal in the future. Although the relevant system equipment manufacturers have suffered the impact of the epidemic, they are actively grasping the turning point of the industry.

Passive components are components found in electronic products that consume rather than generate energy, such as resistors, capacitors, and inductors. Trillions of these common basic components are manufactured every year. They are cheap to manufacture, and can be produced using a large variety of materials. Most are general-purpose types, but some are specially designed for niche markets.

Manufacture all related machinery and design, replace manpower with mechanization, fully reduce personnel costs and increase efficiency, the upstream part is mostly component suppliers, the downstream is the manufacture of terminal machinery products, most of them are engaged in industrial machinery, responsible for assisting other industries in manufacturing and work.

A service robot is defined as improving the quality and convenience of human life. It provides semi-automatic or fully automatic services through the combination of a mobile base and a robotic arm and is equipped with a controller device.

An Industrial PC, referred to as IPC, mainly refers to a personal computer that is specially used in the industrial world and can be used as a manufacturing controller.

Electronic components are the basic components combined together to make complete electronic products. Understanding the functions, types, structures, and properties of commonly used electronic components is fundamental to understanding electronic technology.

A light sensor is a sensor that converts light signals into electrical signals using photosensitive elements. The light sensor is usually composed of both a light projector and light receiver. Light sensors are generally composed of three elements: a light source, an optical path and optoelectronic components. The measured optical changes are converted into changes in electronic signals with the help of photoelectric components. With the growth and development of Internet of Things technology, the application of light sensors is entering all aspects of daily life.

Any electronic product must use two components, so-called "active components" and "passive components". "Active components", as the name suggests, are components that can actively perform operations independently, while "passive components" play a passive protective role. When an electronic product changes current or voltage, the role of "passive components" is to protect "active components" by means of lowering voltage, filtering noise, etc. To put it simply, "passive components" with low unit prices are always ready to protect the safety of "active components" with high unit prices.

A charging station is a device that supplies electric energy for electric vehicles (including pure electric vehicles and plug-in hybrid electric vehicles), similar to the gas station used in fuel vehicles. How does it work and in what scenarios? Let’s find out.

Through virtual power plants, the integration of distributed energy such as renewable energy, energy storage equipment, and backup power has become a new science in energy management. As the proportion of renewable energy gradually increases, to solve the problem of intermittent power supply, flow batteries that can store electricity for a long time have attracted much attention.

KVM switches allow you to control multiple computers from a single keyboard, monitor and mouse, increasing productivity, saving space and money. This exclusive feature also provides IT administrators with multiple computers or servers, centralized real-time updates and maintenance.

Electronic connectors are also often referred to as circuit connectors, electrical connectors, and conductor devices that bridge two conductors on a circuit so that current or signals can flow from one conductor to another. An electronic connector is a motor system that can provide a separable interface to connect two secondary electronic systems. Simply put, the components used to complete the electrical connection between circuits or electronic machines are called connector.

Many people do not know about switching power supply and have always thought that is similar to a linear power supply. Actually, there is difference. The following will explain the principles of basic regarding switching power supplies. Learn with us now!

The negative electrode material refers to the raw material that constitutes the negative electrode in the battery. The negative electrode of lithium-ion battery is made of negative electrode active material carbon material or non-carbon material, binder and additive to make paste glue, which is evenly spread on both sides of copper foil, dried and rolled. The key to the successful fabrication of lithium-ion batteries lies in the preparation of negative electrode materials that can reversibly de/intercalate lithium ions.

The AC voltage is stepped down to the proper AC voltage through a transformer.
