☀️The main factors affecting the dissipation factor of film capacitors are frequency, temperature, humidity and so on. ❓What is the relationship between dissipation factor and frequency? ✨If the inductive reactance Ls is not considered, for ƒ <ƒt (where ƒt is the resonant frequency), the equivalent circuit of the capacitor shows that the disipation factor tanδ is [...]
The aging characteristics of the class Ⅱ of ceramic capacitors ☀️Ageing is a unique characteristic of ceramic capacitors. As the time of delivery of ceramic capacitors increases, the capacitance of the capacitor decays. The Class Ⅰ of ceramic dielectric capacitor has no aging phenomenon; the Class Ⅱ of ceramic capacitor has an aging phenomenon. ☀️The capacitance of [...]
The relationship between capacitor voltage and operating temperature ⛳️For organic films, when the temperature rises to a certain level, the film begins to soften, and the withstand voltage will be greatly reduced at this time. Therefore, organic film capacitors must not work at excessively high temperatures. If they must work at high temperatures, they must be [...]
What is the function of the welding robot's control system? Welding robots can increase the speed of enterprise production lines, stabilize welding quality, and save enterprise costs in terms of production expenditure. There is a big difference from traditional welding. Thanks to the control system of welding robots, the editor will show you the control of [...]
Characterization parameters of electrolytic capacitors-Leakage Current, Rated Voltage, Capacitance Temperature Change Rate. 🔔 Today we will introduce: leakage current (I), rated voltage (U), and capacitance temperature change rate. 🔺1.1.1 Leakage current (I) 📌The leakage current of an electrolytic capacitor is used to characterize its insulation, which is equivalent to the insulation resistance parameter of other types [...]
