Power supply high frequency filter capacitor selection skills 1) Theoretically, the impedance of an ideal capacitor decreases as the frequency increases (1/jwc), but due to the inductive effect of the pins at both ends of the capacitor, the capacitor should be regarded as an LC series resonant circuit, and the self-resonant frequency is The FSR parameter [...]
Which capacitor is more suitable for filter circuit? Many electronic designers know the role of filter capacitors in the power supply, but the filter capacitors used at the output of the switching power supply are not the same as the filter capacitors selected in the power frequency circuit. They are commonly used as filters in the [...]
The decoupling capacitors is a capacitor installed on the power supply terminal of the component in the circuit. This capacitor can provide a more stable power supply, and can also reduce the noise of the component coupled to the power supply terminal, and indirectly can reduce the influence of other components on the noise of the [...]
