Breakdown Mechanism of Ceramic Capacitor under High humidityThe breakdown failure of semi-sealed ceramic capacitors (such as patch capacitors) in high humidity environment is a common and serious problem. The breakdown can be divided into dielectric breakdown and surface arc breakdown. The dielectri

The consequences of silver ion migrationMost inorganic dielectric capacitors use silver electrodes. When semi-sealed capacitors work at high temperature, water molecules infiltrating into the capacitors produce electrolysis. The oxidation reaction occurs at the anode and the silver ion binds with th

Effect of moisture on deterioration of Electrical parameters When the humidity in the air is too high, the water film is condensed on the surface of the capacitor shell, which can reduce the surface insulation resistance of the capacitor. Here, for a semi-sealed structure capacitor, moisture can als

5.To control the operating temperature, it is generally required that the temperature of the hot spot of the shunt capacitor shell should not be greater than 60 ℃ under normal environment, otherwise, the cause must be found out and the treatment should be carried out.6.Pay attention to inspect, chec

3.Fuse protection shall be provided for each single CBB capacitor requiring that the rated current of the fuse shall not be greater than 1.3 times the rated current of the protected capacitor. In this way, the failure of one capacitor can be avoided, and the group explosion accident will be caused b

1.To deal with the abnormal operation condition in time, it is found that the shunt capacitor has abnormal conditions such as blooming, joint heating, serious oil leakage and so on during operating, so it must be withdrawn from operation. For the malignant accidents such as oil injection, fire, expl

No polarity, high insulation impedance, excellent frequency characteristics (wide frequency response, and small dielectric loss), Based on the above advantages, thin film capacitors are widely used in analog circuits.Especially in the intersecting part of the signal, it is necessary to use capacitor

Chinese name for CBB capacitors:, usually followed by two numbers, such as CBB60/CBB65. 0 and 5 are the CBB film capacitor serial code rule: ( 0: axial extraction; 1: radial extraction; 2: DC voltage; 6: ac voltage; 8: DC high voltage)Common specifications in the CBB capacitor market areCBB11 CBB12
