TTI KEMET Facedown Capacitors
Any time design engineers talk about low inductance capacitors, it is usually assumed that the only type of low inductance capacitors is MLCC, but this is no longer the case. By changing the package configuration of the SMD conductive-polymer capacitor, inductances lowered by 75% are available today and inductances approaching 100pH will soon be available. Because this component is by its physical structure a lossy component, achieving impedances below 5 milliohms extends through a significant frequency range unlike the very low sharp and narrow impedance responses of the ceramic capacitors.
