There are two main categories of components and these can be broken down into active components and passive components. An active component will rely on a source of energy and can usually give power to a circuit. This can include amplifying components such as vacuum tubes (valves), tunnel diodes and transistors. The passive components, as the name points to, cannot give or introduce power into the circuit they are attached or connected to. As such, they cannot increase the power of a signal by themselves. Some of the more interesting trends for electronic components have been rising in popularity over the last few years and include:
1. A printed circuit, or printed circuit board
(PCB), which is a thin plate on which chips and other electronic components are placed on. A PCB is made of conducting components, inductor contacts, resistors and capacitors. You can find PCB's in computers, which usually have one or two boards, or cards. As more and more people use computers, this is an electronic component that continues to grow in the areas of technology and information.
2. The manufacture of bare printed circuit boards is also a very big industry these days, especially in China, where many of them are produced. Establishments that are based abroad commonly manufacture printed circuit boards as well as specialized electrical components. Bare, also known as rigid or flexible, circuit boards do not have mounted electronic components. As such, companies need to print, plate, screen, or photoprint various paths for electrical currents on separate laminates.
3. Electronic connectors are the last trend that can be seen in both the United States and industries found abroad. These connectors consist of a wide variety such as coaxial, cylindrical, rack and panel, printed circuit and fiber optic. One drawback to the changing technologies is that many connectors become obsolete, making them hard to find for older electronics. However, various online companies and manufacturers specialize in specific connectors and parts and can help you with your search.
In today's modern world, it would be impossible to live without any of these electronic components. They are found in almost every PC part and are the fundamental building blocks of electrical and electronic circuits and you will also encounter circuits on motherboards, hard disk logic boards and video cards. Electronic components can also be used and combined with each other and a few of the more well-known components include inductors, resistors, and transformers.
