1 Snap-in electrolytic capacitor—Packaging form Snap-in electrolytic capacitor—are medium and large electrolytic capacitors, most of which are directly mounted on the circuit board. Since snap-in electrolytic capacitors come in a wide range of sizes, different pin patterns are required for reliable mounting on the [...]
1 How electrolytic capacitors work—Inverter arc welding power supply working mode How electrolytic capacitors work—Inverter arc welding power supply is a special working mode of high-power switching power supply. Its particularity is not only that the working characteristics of arc welding require constant current, [...]
1 Working status of electrolytic capacitors—The role of electrolytic capacitors in flyback switching power supplies 1.1 AC input power filter circuit Working status of electrolytic capacitors - low-power switching power supplies are widely used, requiring the cost to be as cheap as possible, the [...]
Most of today's electrolytic capacitors are used in power frequency or high-frequency rectification and filtering of power electronic circuits, power supply bypass with high ripple current, etc. Therefore, in addition to the traditional performance of capacitors: rated voltage, capacitance, loss factor, leakage current, modern [...]
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 [...]
