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:On the ground resistance, what role the capacitor
High-frequency vibration elimination: the capacitor used in the high-frequency vibration circuit called high-frequency vibration capacitor, in the audio negative feedback amplifier, in order to eliminate the vibration may occur high-frequency self-excited, the use of this capacitor circuit to eliminate the amplifier Possible high frequency whistling
Q:Use capacitance to do transformer how to calculate
Similarly, we can also 5W / 65V bulb and 1uF capacitor series connected to the 220V / 50Hz AC, the bulb will be lit, and will not be burned. Because the 5W / 65V bulb operating current is also about 70mA. Therefore, the capacitor buck is actually using capacitive current limiting. While the capacitor actually functions as a limiting current and dynamically distributes the voltage across the capacitor and the load.
Q:What is the electrolytic capacitor inside?
Electrolytic Capacitor Features 1: the capacity of the unit volume is very large, tens of tons to several hundred times larger than other types of capacitors. Electrolytic capacitor features two: rated capacity can be very large, you can easily do tens of thousands of μf or even f (but not with the electric layer capacitance ratio).
Q:Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?
This impedance can not be ignored in the presence of high frequency current, with particular note that the bypass capacitor needs to pass through the two vias when connecting the power plane and the formation so that the parasitic inductance of the vias is multiplied.
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 does the capacitor work? What does it do?
Straight to pass on the circuit need to pass the AC signal, power supply filter, cut off DC and other places to use. Capacitor charge and discharge is the basis of other properties. There are two kinds of filtering, one is the power filter, which is more obvious charge and discharge, can be seen as a container.
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 difference between polyester film capacitors and ceramic capacitors?
Good stability. From the chemical performance, acid, alkali, salt and water corrosion of ceramic materials is very small, from the heat resistance, the ceramic material in the high temperature of up to 500 ~ 600 ℃, long-term work without aging
Q:What are the differences between capacitors and capacitors?
Capacitance, resistance, inductance is physical quantity. Capacitors, resistors, inductors are components that have a specific physical quantity (capacitance, resistance, inductance).
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.
