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 use of capacitors?
As a passive component of the capacitor, its role is nothing more than the following; applied to the power circuit, to achieve bypass, decoupling, filtering and energy storage role, the following classification:
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: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: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: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:Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?
In the design of high-speed digital circuits, the parasitic inductance of the vias is often more harmful than the parasitic capacitance. Its parasitic series inductance will weaken the contribution of the bypass capacitor, reducing the filtering efficiency of the entire power system. We can use the following formula to simply calculate a parasitic inductance of a vias:
Q:What is the phase-shifting capacitor, what is the difference between it and the general capacitor
And the phase-shifting capacitor has the function of changing the phase of the alternating current signal in addition to the characteristics of the general capacitor. The answer can be compensated by the power factor compensation in parallel with the phase-shifting capacitor, and the phase-shifting capacitor can be used to produce the phase-shifting capacitor fault diagnosis device.
Q:Cd capacitance to express what
No capacitance is used in the high-frequency circuit of a capacitor, this capacitor without pins or pins shorter, commonly used in the tuner; generally PF level, the so-called "no sense" is the capacitor work is not produce "inductance" Effect, because C (capacitance) + L (inductance) = R (resistance), (when the match is good), if so, the circuit will not work.
Q:What is the difference between the power capacitor and the complement?
In fact, in the case of three-phase imbalance, but also a total complement and sub-all have, the three-phase power factor, respectively, 0.53,0.67,0.71, then, in the 0.71 above this part, The reactive power required by the other parts of the two phases is compensated by tipping.
Q:What is the relationship between capacitance and voltage?
when you charge 5v, want to be in the first The capacitor is full, the second capacitor half; if you charge a higher voltage 6v, then the first capacitor to diffuse out, the actual performance of the capacitor was breakdown!
