  • 2020-11-11The development situation of film capacitors

    In the past 20 years, film capacitors have made great progress. The volume and weight of capacitors have been reduced by 3 to 4 times, and the technology has also been greatly improved.

  • 2020-11-11Tantalum capacitor knowledge

    Tantalum capacitors are full name tantalum electrolytic capacitors, which are also a kind of electrolytic capacitors. They use metal tantalum as the medium. Unlike ordinary electrolytic capacitors, they do not use electrolyte. Tantalum capacitors do not need to use aluminum-plated capacitor paper

  • 2020-11-11Charging and discharging of capacitors

    Capacitance is an inherent characteristic of a capacitor, which is only related to the area of the two plates, the distance between the plates and the medium between the plates, and it has nothing to do with whether the capacitor is charged or how much it is charged. There is capacitance between any two conductors. A capacitor has a withstand voltage value. When the voltage applied between the two...

  • 2020-11-10Capacitor dielectric materials and thermal properties

    The maximum allowable temperature of a capacitor generally depends on the medium, and the maximum allowable temperature rise of the medium depends on its heat resistance, the change of electrical properties with temperature and the influence of temperature on aging, that is, it depends on the nature of the medium.In some cases, the maximum allowable temperature of a capacitor does not depend on it...
