Low Inductance Capacitors
LOW INDUCTANCE CHIP CAPACITORS The total inductance of a chip capacitor is determined both by its length to width ratio and by the mutual inductance coupling between its electrodes.

Why multiple capacitors in parallel?
The effective ESR of the capacitors follows the parallel resistor rule. For example, if one capacitor''s ESR is 1 Ohm, putting ten in parallel makes the effective ESR of the capacitor bank ten times smaller. This is especially helpful if you expect a high ripple current on the capacitors. Cost saving. Let''s say you need a large amount of

Do decoupling capacitors add capacitance?
In general, when placing decoupling capacitors in parallel, their capacitances add and their compound ESR is reduced (like for parallel resistors). But I am a bit uncertain if/how this applies to their inductance, which is the most crucial aspect in high frequency decoupling.
Should I add a high value polarised capacitor in parallel?
