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:Capacitance for AC and DC effects?: This current is also a sine wave, but with the resistance is different, although there is voltage current, but does not consume energy, called reactive power.

Q:Cd capacitance to express what: Using polypropylene film as a medium, with a special electrode to the cylindrical core connected into a series structure, the core wrapped plastic tape, both ends with flame retardant epoxy resin package. With a small self-inductance, equivalent series resistance is low, loss is small, high insulation resistance, good frequency characteristics and can withstand high voltage, high current impact and other characteristics.

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 kind of capacitance can be divided into?: Aluminum electrolytic capacitor It is made of aluminum cylinder negative, which is equipped with liquid electrolyte, insert a curved aluminum belt made of positive electrode. Also need to go through the DC voltage treatment, so that the formation of an oxide film on the positive film to do the media. It is characterized by large capacity, but large leakage, large error, poor stability, often used for AC bypass and filter, when the request is not high when used for signal coupling. Electrolytic capacitors are positive and negative points, the use can not be reversed. There are positive and negative polarity, the use of time, positive and negative do not reverse.

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!

Q:How to identify high voltage capacitors is good or bad: Test the resistance at both ends with a multimeter. If the use of a pointer multimeter, and most of the same capacitor, you can see the pointer from small to large a swing process. The difference is not the last return to infinity, but 10m. Inexperienced friends may think that the capacitor breakdown or leakage, in fact, not.

Q:Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?: With the increase in stray inductance, IGBT turn-on loss will be reduced, the diode loss will increase. Stray inductance may also cause oscillations, such as oscillations caused by current mutations, which may result in limited device use due to EMI or overvoltage limits.

Q:What is the capacitor, what is the use, where is there?: The role of the capacitor filter, coupling, bypass, decoupling function. Capacitors are mainly used for AC circuits and pulse circuits, in the DC circuit capacitors generally cut off the role of DC. Capacitors do not produce nor consume energy, are energy storage components.

Q:What is the difference between polyester film capacitors and ceramic capacitors?: Different components of the ceramic, its dielectric constant and temperature coefficient is different, the temperature coefficient range is wide, easy to make different temperature coefficient of the capacitor, used as a temperature compensation capacitor.

Q:Is the capacitor attached to the carbon foil positive?: In order to facilitate the manufacture of capacitors, usually the electrolyte solution is immersed in special paper, and then with a place of aluminum and immersion in electrolyte solution with the paper together, so you can more easily in the original aluminum foil to lead the negative.
