Product Description:

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: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: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:What is the difference between the power capacitor and the complement?
Input compensation: three-phase co-fill capacitor input, the three groups of capacitors at the same time. The sub-capacitor can be put into operation separately.
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:Why some Y capacitor is very small, and some Y capacitor is very large?
As a capacitor of the Y capacitor, it is required to obtain the certification of the safety inspection mechanism. Y capacitor appearance is mostly orange or blue, are generally marked with safety certification mark (such as UL, CSA and other logo) and pressure AC250V or AC275V words. However, its true DC withstand voltage is above 5000V. It must be emphasized that the Y capacitor can not be used with a nominal capacitor such as the nominal voltage AC250V or DC400V.
Q:Use capacitance to do transformer how to calculate
Capacitance buck method: For example, we will be a 110V / 8W bulb and a 1uF capacitor in series, received 220V / 50Hz AC voltage, the light bulb is lit, the normal brightness will not be burned. Since the 110V / 8W bulb requires a current of 8W / 110V = 72mA, it is consistent with the current limiting characteristics of the 1uF capacitor.
Q:What are the differences between capacitors and capacitors?
Capacitance is a large category, and capacitors are subclasses of capacitors. Capacitors can be divided into cbb capacitors, aluminum electrolytic capacitors, safety capacitors and so on. Different categories, the difference is still relatively large
Q:What is the difference between the reactor and the capacitor?
Capacitors in order to boost, so that the voltage ahead; reactor in order to buck, so that the voltage lag; they are in the system are reactive power, improve power quality
Q:What kind of capacitance can be divided into?
The paper dielectric is made of two pieces of metal foil, made of very thin capacitor paper, rolled into a cylindrical or flat cylindrical core, and then sealed in a metal shell or insulating material (such as paint, ceramics, glass glaze, etc.) production. It is characterized by a smaller size, capacity can be done bigger. But there are inherent inductors and losses are relatively large, suitable for low frequency.
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.
