Product Description:

Case: Round aluminum oil-filled and sealed case.

AC film capacitors for general purpose applications (e.g. AC filters with harmonic frequencies exceeding 60 Hz), as well as for lighting.For the latter, AC capacitors are used in conjunction with asynchronous motors on single-phase mains supplies. They are designed for 50 or 60 Hz systems.


Applications:Mainly used for fishing lamp and metal halide lamp.

Q:What is the relationship between capacitance and voltage?
In your case, you can think of two capacitors as two containers, 5v capacity than 10v half (because they are 0.01uF),
Q:Capacitance for AC and DC effects?
Current waveform ahead of the voltage 90 degrees, in a sine wave cycle, half of the time ( Voltage waveform 0-90 degrees and 180-270 degrees) power to charge the capacitor, while the other half of the time (voltage waveform 90-180 degrees and 270-0 degrees) capacitance of the power discharge, the power and intact return power The
Q:Low voltage capacitor voltage 0.45 and 0.4 What is the difference between usage
Can be used in the low-voltage three-phase power lines on the line, but the level of different pressure, connected to the 400V line, 450V capacitor capacity is 79% of rated capacity, 400V capacitor capacity is rated capacity. In the use of life on the 450V longer than 400V
Q:How to judge the capacitor is good or bad?
Due to the amplification of the composite transistor, the measured capacitance of the charge and discharge process to be amplified, so that the multimeter pointer increase the amplitude, so easy to observe. It should be noted that: in the test operation, especially in the measurement of small capacity capacitance, it is necessary to repeatedly change the measured capacitance of the pin contact A, B two points, in order to clearly see the multimeter pointer swing.
Q:What is the principle of capacitance isolation?
When the supply voltage rises in the reverse direction, the capacitor is charged in the reverse direction, and then the discharge is reversed. So the charge and discharge and the AC current is really the same, so the capacitor can pass the AC current.
Q:What is the difference between polyester film capacitors and ceramic capacitors?
Polyester capacitor medium for the polyester film, its capacity and pressure range, small size, large capacity, high temperature, low cost. But tgδ with the frequency changes, it is used for tgδ, stability and loss requirements are not high occasions, such as DC and pulsating circuit.
Q:How to use the capacitor
Circuites that are forbidden use: Even if the customer installs a solid-state aluminum capacitor in strict accordance with the welding conditions we have given, the leakage current of the solid-state aluminum capacitor may also increase or even increase significantly.
Q:Why does the circuit current gradually decrease when charging the capacitor?
For the ideal capacitor, when the capacitor is charged, as the voltage across the capacitor gradually increases, the charging current will gradually decrease until zero.
Q:On the ground resistance, what role the capacitor
Decoupling: The capacitor used in the decoupling circuit is called the decoupling capacitor. This capacitor circuit is used in the DC voltage supply circuit of the multi-stage amplifier. The decoupling capacitor eliminates the harmful low frequency cross-connection between the amplifiers.
Q:What is the electrolytic capacitor inside?
Electrolytic capacitor inside the composition of the structure: two close to each other with a coating with polarity, positive and negative metal electrode plate, the middle folder with insulating material (medium for the electrolyte,) constitute
