    一、 Improper selection of current within the range Improper selection of current within the range,the locations where more voltage is generated are the dc maintenance and simple harmonic oscillation parts.If the current value required by the essence is greater than the current value allowed to pass
  • [industry information] How to effectively extend the life of CBB capacitors
    2024-05-29
    Method 1: Carefully control the starting voltage and the operating voltage of the parallel capacitor, and make sure they are within the allowable range.That is, the long-term operating voltage of the CBB capacitor cannot be greater than 10% of its nominal voltage value. If the operating start-up vol
  • [industry information] How to purchase air conditioner capacitors?

    1. When purchasing a capacitor, first observe the appearance of the capacitor to see if it is deformed or cracked. If so, do not buy it. There must be quality problems.In addition, you should also pay attention to see if it is the same model as the previous one. Do not buy any model randomly, as thi
  • [industry information] How to judge whether the starting capacitor is broken
    2024-04-25
    1. Look: Check whether the capacitor is bulging or swelling; 2. Listen: Connect the motor and listen to see if there is a buzzing sound from the motor. Turn the rotor by hand to rotate slowly and weakly; 3. Smell: Some capacitors are burnt due to excessive current and have a burning smell
  • [industry information] How to select the withstand voltage value of electric fan starting capacitor
    2024-04-13
    The ac motor of an electric fan generally requires a starting capacitor. The capacitance mainly depends on the capacity and voltage resistance value.How to choose the withstand voltage value of electric fan starting capacitor?In order to ensure that the electric fan can operate reliably and stably,
  • [industry information] What impact does the starting capacitor have on the crystal oscillator output frequency?
    2024-04-03
    A: What impact does the starting capacitor have on the crystal oscillator output frequency?Q: Mainly frequency correction. Explanations:1. The larger the starting capacitance, the more negative the frequency of the crystal oscillator is; conversely, the smaller the starting capacitance is, the more
