Voltage, temperature, capacity and equivalent resistance are several important parameters of capacitance, and the lower the ESR is, the better its quality is. ESR is related to capacitance, frequency, voltage, temperature and so on.When the voltage is fixed, the larger the capacity, the lower the ESR. In the design of the board, several small capacitors are used to connect with the limit of PCB space, and many people think that the lower the number of parallel small resistors, the better the effect will be. This is true in theory, but considering the impedance of the solder joint of the capacitor foot, the effect is not necessarily outstanding if several small capacitors are connected in parallel. Sometimes there is nothing wrong in theory, but in practice we have to consider our own factors.
