$begingroup$ A current impulse (infinite di/dt) can only pass through a perfect inductor if the terminal voltage across the inductor is infinite. In a practical world, an inductor has self-capacitance and this means the impulse current bypasses the "magnetic" side of things and appears to pass through the inductor, but it doesn''t theoretically.
If we use a capacitor that has a decoupling capacitor, so shunted to ground, then why for a DC source do we say the capacitor acts like a short at startup (t=0) thus having a high inrush but according to the top paragraph a DC source has a 0 Hz frequency so it has a very high impedance. This clearly is a contradiction.

The capacitor may survive many repeated applications of high voltage transients; however, this may cause a premature failure. OPEN CAPACITORS. Open capacitors usually occur as a result of overstress in an application. For instance, operation of DC rated capacitors at high AC current levels can cause a localized heating at the end terminations.
When used on DC supplies a capacitor has infinite impedance (open-circuit), at very high frequencies a capacitor has zero impedance (short-circuit). All capacitors have a maximum working DC voltage rating, (WVDC) so it is advisable to select a capacitor with a voltage rating at least 50% more than the supply voltage.

While open-mode MLCCs greatly reduce the risk of short-circuit failures, it should be noted that the probability of such failures is still not zero. If the probability of short-circuit failure must be reduced further still, the use of two series-connected devices oriented at 90° relative to each other has been suggested in industry literature.
