For decoupling capacitors, the parasitic
inductance generated by the capacitor needs to be
small so that the resonant frequency is higher. The
parasitic inductance will add noise voltage spikes to
the power line voltage as shown in the following
equation:
Internal structure of the standard MLCC
TDK Flip Type capacitor offers industry standard
case sizes in “flip” geometry construction which allows lower
ESL than standard capacitors. By rotating the orientation of the
capacitor 90º, the current path through the unit is shorten and
effectively lowers the parasitic inductance value. The flip
Internal structure of the Flip Type MLCC
geometry requires the termination to be applied along the
length instead of the width of the MLCC. Flip Type series are
available in four case sizes with voltage from 4V to 16V.
Reduced ESL is necessary for noise decoupling in high speed applications;
these Flip Type capacitors are typically placed around ASICs as well as on the CPU
power line for decoupling purposes.
δi/δt can be very large when operating under very high frequency, where L is the
parasitic inductance. In order to stabilize the power line without adding anymore noise
from the capacitor, parasitic inductance needs to be small. Because of the unique
design of the Flip Type capacitor, the parasitic inductance is lower than the traditional
multilayer ceramic capacitor (MLCC). Therefore, the Flip Type MLCC is very effective
for high speed decoupling applications.
