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 and motor run applications. 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:Asynchronous motors、Air conditioning、Domestic appliances、Compressors/pumps/garage、door openers、 Awning drives、 Heat pumps ets.

Q:Why some Y capacitor is very small, and some Y capacitor is very large?
To charge the power cord for long periods of time. The safety standard stipulates that the voltage (or ground potential) charged at both ends of the power cord plug must be less than 30% of the original rated operating voltage within two seconds when the machine power cord is in operation.
Q:What is the electrolytic capacitor inside?
Electrolytic capacitor is a dielectric of a dielectric electrolyte coating has a polarity, positive and negative can not be connected wrong. Electric capacity (Electric capacity), by the two metal pole, the middle folder with insulating material (medium) composition.
Q:On the ground resistance, what role the capacitor
The capacitor used in the bypass circuit is called the bypass capacitor. If the signal is removed from the signal in the circuit, the bypass capacitor circuit can be used. According to the frequency of the removed signal, there is a full frequency domain (all AC signals ) Bypass capacitor circuit and high frequency bypass capacitor circuit.
Q:Why does the circuit current gradually decrease when charging the capacitor?
Why does the circuit current gradually decrease when charging the capacitor? Because the charge began to charge the capacitor, the capacitor two electrode plate charge began to zero, the electrostatic field is zero, the absorption of electrons is not exclusion, the performance of the phenomenon is the beginning of the charge when the circuit current is very large, with the capacitor The charging time increases, there will be more and more charge adsorption on the capacitor two electrode plates,
Q:Capacitance for AC and DC effects?
In the sine wave AC circuit, the current size of the current flowing through the capacitor can be quantitatively calculated. Specifically, the voltage U is in volts (V), the current I is in the unit (A), the capacitance C is expressed by the law (F) (Ω), the frequency of the AC power supply is expressed in Hertz (Hz) units, and the frequency of the AC power supply is expressed in Hits (Hz)
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:Use capacitance to do transformer how to calculate
According to this feature, if we connect a resistive element in series with a 1uF capacitor, the voltage obtained at both ends of the resistive element and the power dissipation it generates depends entirely on the characteristics of the resistive element.
Q:What kind of capacitance can be divided into?
Capacitors are often called capacitors. According to its structure can be divided into fixed capacitors, semi-variable capacitors, variable capacitors three.
Q:How does the capacitor work? What does it do?
The bypass capacitor is an energy storage device that provides energy to the local device, which can equalize the output of the regulator and reduce the load demand. Like a small rechargeable battery, the bypass capacitor can be charged and discharged to the device. To minimize the impedance, the bypass capacitor should be as close as possible to the load device's power supply pin and ground pin.
