Product Description:

Case:Round aluminum oilfilled and sealed case with M8 screw,quick connector terminals,anti moisture,anti explosion,good self-healing,good insulation etc.

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 etc.

Q:On the ground resistance, what role the capacitor
Coupling: The capacitance used in the coupling circuit is called the coupling capacitor, which is used in the capacitive coupling amplifier and other capacitive coupling circuits to make use of this capacitor circuit.
Q:What is the difference between the power capacitor and the complement?
A total of three-phase compensation at the same time, sub-compensation is a single-phase compensation.
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:Is the capacitor attached to the carbon foil positive?
The negative electrode of the capacitor is made of electrolyte, the electrolyte is generally composed of boric acid, ammonia, ethylene glycol and other components.
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.
Q:How to use the capacitor
Solid-state aluminum capacitors have positive and negative points, do not reverse the solid-state aluminum capacitors, reverse solid capacitors can lead to a sharp increase in leakage current or reduced service life.
Q:What is the difference between polyester film capacitors and ceramic capacitors?
Ceramic dielectric (type CC) ceramic material dielectric constant ε is very large, so the capacitor volume can be made very small.
Q:What is the relationship between capacitance and voltage?
The larger the capacity of the capacitor, the larger the voltage, the smaller the capacity (uF). Since q = Cu, q is the current charge number of the capacitor, which is substantially proportional to the volume of the capacitor
Q:Cd capacitance to express what
Mainly speaking, the winding process of the capacitor is a non-inductive winding structure (relative, there is a sense of winding structure), in fact, no sense of capacitance is not no inductance, but the inductance is very small, for high-frequency operation of the capacitor, We emphasize no sense. In fact, the inductance is small. From this point of view, almost all of the metal film capacitors are no sense
Q:Why does the circuit current gradually decrease when charging the capacitor?
due to the increase in the number of charge, the electrostatic field field strength will gradually increase, increasing the field strength caused by the absorption of electrons to produce exclusion, So that the number of adsorbed charges gradually reduced, the number of charge to reduce the performance of the phenomenon that the charging current is gradually reduced. When the number of charges on the two electrode plates of the capacitor reaches a gradually increasing field strength constraint, the amount of charge is not increased and the equilibrium state is reached, that is, the charge saturation current is zero.
