Q:Does the size of the capacitor affect the power consumption?

The capacitance of the symbol is C. In the international unit system, the capacitance of the unit is Farah, referred to as the law, the symbol is F. a capacitor, if the battery with a library when the potential difference between the two is 1 volt, the capacitor capacitor is 1

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:

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:Is the capacitor attached to the carbon foil positive?

Electrolytic capacitors of the positive plate with aluminum foil, immersed in the electrolyte for anodic oxidation treatment, aluminum foil surface will produce a layer of aluminum oxide film, the thickness is generally 0.02 - 0.03μm. This layer of oxide film is positive and negative insulation between the plates.

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:On the ground resistance, what role the capacitor

The capacitor used in the bypass circuit is called the bypass capacitor. If the signal is removed from the signal in the circuit, the bypass capacitor circuit can be used. According to the frequency of the removed signal, there is a full frequency domain (all AC signals ) Bypass capacitor circuit and high frequency bypass capacitor circuit.

Q:Why some Y capacitor is very small, and some Y capacitor is very large?

In line between the line of fire and zero line suppression capacitor, commonly known as X capacitance. As the location of the capacitor connection is also more critical, the same need to meet the relevant safety standards. X capacitance is also one of the safety capacitors. According to the actual needs, the capacitance value of the X capacitor is larger than the capacitance of the Y capacitor. However, it is necessary to connect a safety resistor in parallel with the X capacitor to prevent the charging and discharging of the power supply line.

Q:Low voltage capacitor voltage 0.45 and 0.4 What is the difference between usage

0.45 capacitor used in the voltage level is high (for example, the transformer low voltage side voltage may reach 415V), with a tuned reactor (tuning reactor will increase the capacitor terminal voltage) situation; Note that the actual capacity of 0.45 capacitor nominal capacity (Actual voltage / 0.45) ^ 2 times;
