Introduction to Inductive Reactance16 April 2021
Alternating current can also pass through the coil, but the inductance of the coil has an obstructive effect on the alternating current. This obstruction is called inductive reactance.
What is a Fixed Inductor?15 April 2021
Fixed inductors are a classification of inductors according to their structure, and fixed inductors are commonly used inductive devices. An inductor with a fixed inductance is called a fixed inductor (or a fixed coil), and it can be a coil with a single layer, multiple layers, honeycomb type, or a magnetic core. These coils are winded on the magnetic core using a wire of corresponded diameter and they are packaged with epoxy resin or plastic according to the inductance and the maximum DC operating current.
What is FPC (Flexible Printed Circuit)?14 April 2021
Flexible Printed Circuit (FPC) is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film. It has the characteristics of high wiring density, lightweight, thin thickness, and good bendability.
What is an Application-specific Integrated Circuit?13 April 2021
Application-specific integrated circuits are integrated circuits made for specific users or specific electronic systems. The versatility and mass production of digital integrated circuits have greatly reduced the cost of electronic products and promoted the popularization of computer communications and electronic products. However, at the same time, it has also created the problem of the contradiction between general-purpose and special-purpose, and the disconnection between system design and circuit production.
How to Select a Digital Isolator?12 April 2021
A digital isolator is a chip used to make the electronic system have high resistance isolation when signals and analog signals are transmitted, so as to realize the isolation between the electronic system and its users. The reason why designers introduce isolation is to meet safety regulations or reduce ground loop noise.
An Overview of SD Card12 April 2021
The SD (Secure Digital) card is a new generation of memory devices based on semiconductor flash memory. Due to its small size, data transmission speed, hot-swap, and other excellent features, it is widely used in portable devices, such as digital cameras, tablets, and multimedia players, etc.
What is a Ceramic Filter?10 April 2021
Ceramic filter is a widely used filter that uses rigid microporous material as a filter element. It is composed of ceramic, corundum, silicon carbide, sand chip, and so on. It is mainly used in fluidized bed combustion, calcination, power generation through organic waste gasification, building materials, and other fields.
What is a Thermoelectric Cooler?08 April 2021
Thermoelectric Cooler (TEC) is found in many applications that require precision temperature control. The small size of the TEC allows precision thermal control of individual components such as fiber optics, laser drivers, precision voltage references, or any other temperature critical device.
What is Uninterruptible Power Supply (UPS)?08 April 2021
UPS is an uninterruptible power supply containing the energy storage device. It is mainly used to give a part of a device with a higher power stability, providing uninterrupted power supplies.
How does an Inverter Work?06 April 2021
The inverter is a converter that converts DC electric energy into constant frequency and constant voltage AC or Frequency and voltage modulation AC. It is composed of an inverter bridge, control logic, and filter circuit. Inverters are widely used in air conditioners, home theaters, electric grinding wheels, power tools, DVDs, VCD, computers, TVs, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc.
What is LCD? Working and Types02 April 2021
LCD is a liquid crystal display. The LCD structure is to place a liquid crystal cell between two parallel glass substrates. LCD has replaced CRT as the mainstream, and the price has dropped a lot, and it has become fully popular.
What is an Auto Transformer and Its Working?01 April 2021
Auto transformer refers to a transformer whose primary and secondary windings are on the same winding, and the primary and secondary windings are directly connected in series and self-coupled. According to the structure, it can be subdivided into adjustable pressure type and fixed type. Auto-coupling means electromagnetic coupling. Ordinary transformers transfer energy through the electromagnetic coupling of the primary and secondary coils. There is no direct electrical connection between the primary and secondary sides. The primary and secondary sides of the auto transformer have direct electrical connections. Its low-voltage coils It is part of the high voltage coil. Protective equipment such as auto transformers are also used in protective equipment for communication lines.
