1 Historical development of supercapacitor Supercapacitor first appeared in the middle of the 18th century. Pieter Van Musschenbrock of Leiden University in the Netherlands and Ewald Geory Von Kleist of Germany developed the Leyden jar, which is recognized as the prototype of all capacitors. [...]
What are the differences between solid capacitors and electrolytic capacitors? Solid capacitors and electrolytic capacitors are two capacitor products that we are more familiar with. Each of these two capacitors has its own functions and advantages. Different electrical appliances choose different types of capacitors. [...]
The main parameters of the capacitor include capacitance, rated voltage, loss factor, leakage current, and maximum operating temperature. These parameters are required in aluminum electrolytic capacitor data. In addition, aluminum electrolytic capacitors have parameters that are different from other capacitors. In addition to the [...]
1.1 Detection method of common capacitor When testing ordinary capacitors, you can first read the nominal capacitance of the ordinary capacitor to be tested according to the identification information of the ordinary capacitor, then use a multimeter to detect the actual capacitance of the [...]
Capacitors are represented by the letter "C" in circuits. The unit of capacitance is "farad", referred to as "law", represented by the letter "F". In practice, "microfarad" (expressed in "μF"), "nanofarad" (expressed in "nF") or picofarad (expressed in "pF") is more commonly used. The [...]
Carbon nanotubes Carbon nanotubes (CNT), also known as bucky tubes, belong to the Fullerian carbon system. In 1991, Professor Lijima discovered for the first time a nanometer-sized (1-100nm) multilayer tube, namely CNT, under a high-resolution transmission electron microscope when evaporating graphite electrodes using a [...]
Ceramic capacitors are a type of capacitor that uses ceramic as the dielectric material. They are widely used in electronic circuits due to their high capacitance-to-size ratio, low cost, and stability over a wide range of temperatures and frequencies. There are several ceramic capacitor [...]
Micro ceramic chip capacitors for surface mounting on printed circuit boards are usually available in two types: Single Layer Capacitor (SLC) and Multi-layer Ceramic Capacitors (MLCC). These two types of chip capacitors are widely used in radio frequency circuits and microwave circuits due to [...]
MLCCs are important passive components and were born in the 1960s. Because of its advantages such as high reliability, small size, low loss, and easy placement, it has quickly become the preferred type of capacitor in the electronics industry. With the development of various [...]
Xuansn Electronics Event-Spring outing：This orientation activity allowed new employees to have a deeper understanding of the history and culture of the companyAt the beginning of the new year, Vientiane was renewed, and Xuansn Electronics Co., Ltd. ushered in a group of new faces. In [...]
