FAQ

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.

How does the capacitor work? What does it do?

Capacitance works: the principle of charge and discharge simply put the capacitor is the two poles charged or discharge, that is, charge diffusion. Charge and discharge capacitors should be connected in series, can be connected in parallel; it is the basis of other properties of capacitance. The phenomenon of intermittent communication is the embodiment of charge and discharge, if it is DC, charged to stop, the capacitor charged; if it is alternating current, is constantly charging discharge. Complete the transmission of AC.

What is the phase-shifting capacitor, what is the difference between it and the general capacitor

Assuming a capacitor has upper and lower poles, the upper plate is connected with the positive pole, the lower plate is connected with the negative electrode, connected with the power source, the potential difference between the two plates is formed, and the potential difference between the two electrodes is equal,

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.

How to judge the capacitor is good or bad?

10pF below the fixed capacitor capacity is too small, with a multimeter to measure, only qualitative check whether there is leakage, internal short circuit or breakdown phenomenon.

Capacitance for AC and DC effects?

Current waveform ahead of the voltage 90 degrees, in a sine wave cycle, half of the time ( Voltage waveform 0-90 degrees and 180-270 degrees) power to charge the capacitor, while the other half of the time (voltage waveform 90-180 degrees and 270-0 degrees) capacitance of the power discharge, the power and intact return power The

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!

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.
