Stray Capacitance
In inductors, stray capacitance generates a series of resistance, while in PCB, it is common to see that induced capacitance changes its operating point. All main circuit elements like diodes, inductors, and transistors tend to have internal capacitance, which could cause their behavior or pattern to depart a little from ''ideal'' circuit elements.

Lab Notes on Capacitors
A capacitor is an electrical device for storing charge. In general, capacitors are made from two or more plates of conducting material separated by a layer or layers of insulators. The capacitor can store energy to be returned to a circuit as needed. The capacitance (C) is defined as the ratio of the stored charge (Q) to the potential difference (V) between the conductors:

After many nights staring at datasheets trying to understand the problem, I started to understand how equivalent capacitors and inductors were being formed all over my board.
