improper selection of current in rangeImproper selection of current in the range results in locations which are more likely DC maintenance and simple harmonic vibration part. If the original needed current value is larger than the current value allowed by the thin film capacitor, it will form the th

Application in power electronic circuit. The thin film capacitor is used in this area, which mainly acts as a buffer of electric current, clamping, resonant bypass and restraining the electromagnetic interference of power supply and so on.When the thin film capacitor is used as a bypass, it mainly

Main failure mechanism causing deterioration of electrical parameters of Capacitor. (1) Damp or surface contamination; (2) Silver ion migration; (3) Self-healing effect; (4) Electrical aging and thermal aging of dielectric; (5) Volatilization and thickening of working electrolyte; (6) Electrode corr

Main failure Mechanism of causing Open Circuit Capacitor (1) The "self-healing" occurs in the lead position, which insulates the electrode from the lead wire; (2) The contact surface of the outlet line and the electrode are oxidized, resulting in low level open circuit; (3) Poor contact between the

Main failure mechanism of capacitor breakdown. 1.The dielectric material has blemishes or defects, or contains conductive impurities or conductive particles; 2. Electrical aging and thermal aging of dielectric; 3. Electrochemical reaction in dielectric; 4. Silver ion migration; 5. Mechanical damage

1.Breakdown short circuit; fatal failure. 2. Open circuit; fatal failure-change of electrical parameters (including excess capacitance, increased tangent of loss angle, decreased insulation performance or rising leakage current, etc.) partial function failure. 3. Leakage; partial functional failure.

The main causes of the rupture of capacitor insulator. (1)Mechanical injury; (2)Excessive residual heat during sintering of glass powder insulator; (3)The welding temperature is too high or the heat is not uniform.

The main causes of corrosion or fracture of capacitor leads. (1) Electrochemical corrosion occurs under the action of electric field in high temperature environment; (2) Leakage of electrolyte along lead wire, which causes lead wire to be chemically corroded; (3) The mechanical damage of the lead wi

Main causes of leakage of Capacitor. (1) Under the action of electric field, the impregnating material can separate the liberation gas to make the pressure in the shell one liter; (2) The welding between the metal shell and the sealing cover of the capacitor is not good; (3) The insulation is not we
