FAQ
How to choose a bypass capacitor?
The size of the decoupling and bypass capacitors needs to be determined according to the noise frequency. Capacitors with different capacitance values can eliminate noise at different frequencies. In the circuit design process, each capacitor has an equivalent series inductance. When the operating frequency is higher than the resonant frequency, the capacitor is inductive, and the decoupling and bypass effects will be lost. Therefore, to increase the series resonant frequency, it is necessary to reduce the equivalent series inductance of the capacitor as much as possible. The smaller the capacitance value, the higher the resonant frequency, and the appropriate decoupling and bypass capacitors can be selected according to the application requirements. Decoupling capacitors and bypass capacitors should be selected with low series equivalent resistance as much as possible. The lower the ESR (equivalent series resistance), the easier it is to eliminate noise. The decoupling and bypass capacitors should be as close as possible to the pins of the chip. The placement and routing of the capacitors also directly affect the effect of filtering out interference.
