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: Low voltage capacitor voltage 0.45 and 0.4 What is the difference between usage: 0.45 and 0.4 capacitors are capacitors that rated the line voltage of 0.45kV and 0.4kV; they are suitable for 380V voltage systems, the difference lies in their pressure rating;

Q: What is the phase-shifting capacitor, what is the difference between it and the general capacitor: After the power is turned off, the charge will not disappear, nor will it be neutralized (after all, between the two plates is insulated, positive and negative charge can only attract each other, and can not be combined), so that the potential difference has been there until you To discharge, the bipolar plate with a wire, the electrons along the wire from the lower plate to move to the upper plate, the potential difference disappeared.

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: What is the principle of capacitance isolation?: When the capacitor is connected to the DC circuit, there will be a brief charging process. When the positive and negative plates are filled with charge (when the voltage across the capacitor is equal to the supply voltage), there is no current and then flow, so the capacitor is isolated DC current

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: On the ground resistance, what role the capacitor: Filter: The capacitor used in the filter circuit is called the filter capacitor, in the power supply filter and a variety of filter circuit using this capacitor circuit, filter capacitor will be a certain band of the signal from the total signal removed.

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: 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: 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:
