1. Resonant capacitors with PP film dielectric popular applied for resonant charging,  Frequency Spreading,  Aerospace, Robotics industries;
2. In such electronics, capacitors and inductors have parasitic inductance and capacitance, respectively. Since a capacitor and inductor in series creates an oscillating circuit, all capacitors and inductors will oscillate when stimulated
3.they are capable of storing significant amounts of charge (electrons) in an electrical network (circuit) whereas an inductor 

stores energy in a magnetic field.
