Figures 10 and 11 show the comparative inductance of a conventional MLCC and a FTC, when the capacitor is mounted
on a substrate. The high frequency capability of the FTC is better than a conventional MLCC due to the inductance of a
FTC being less than the MLCC.

The equivalent circuits show parasitic inductances L1, L2 and L3. The resonance frequency (fr) can be determined as
follows:
(Lg = inductance between signal through line and GEN).
The inductance of the FTC (LgFTC = L3//L3 =
) is one quarter that of the MLCC (LgCMC =L3+L3 =L3
× 2).
