Final answer:
The inductors with the highest self-resonant frequencies are chosen because they are effective in impeding high frequencies and act as filters. If an inductor with an SRF lower than the LPFcutoff frequency is chosen, it would result in poor filtering performance.
Step-by-step explanation:
When choosing a ceramic chip inductor, it is beneficial to select the inductors with the highest self-resonant frequencies (SRF). The self-resonant frequency is the frequency at which the inductor's reactance becomes equal to its resistance. By choosing an inductor with a high SRF, we ensure that the inductor will be effective in impeding high frequencies, allowing it to act as a filter for these frequencies.
If we were to choose an inductor with an SRF less than our LPFcutoff frequency, it would result in poor filtering performance. The inductor's reactance would not be high enough to effectively impede the high frequencies, leading to less efficient filtering and potential interference with the desired signal.
