Factors to be considered in the selection of AC coupling capacitors

We know that a series of AC coupling capacitors in the series signal can provide DC bias and overcurrent protection, but this will also bring another problem to the link PDJ (Pattern-Dependent Jitter). The placement of AC coupling capacitors has just been solved, and now we have encountered the value selection problem! Obviously, the AC coupling [...]

Power supply high frequency filter capacitor selection skills

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?

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 [...]

What is a decoupling capacitors?

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 [...]
