![It is well known that the mounting loop of a capacitor owns the major share in parasitic inductance [1]. A practical capacitor when mounted in a printed circuit board has parasitic inductance (L) associated with it. Its equivalent circuit is a series RLC circuit where R represents the loss associated with the capacitor (C). It has a self (series) resonant frequency given byabove which it acts as an inductance. Other important contributors to the parasitic inductance are ESL and plane spreading inductance.](https://static.wixstatic.com/media/b3f48a_c98fb14330e8419dac522806448526e4~mv2.jpg/v1/fill/w_300,h_185,al_c,q_80,enc_auto/b3f48a_c98fb14330e8419dac522806448526e4~mv2.jpg)
