Low inductance (low ESL) surface mount ceramic capacitors are connected directly to the power supply pins of the IC. Short traces or vias are required for this connection to minimize additional series inductance (ESL). Typically a combined network of low ESL MLCC and SMT electrolytic capacitors are used to provide low impedance over wide frequency range, with the larger electrolytic capacitors acting as charge reservoirs, buffering voltage during load stepping transient currents, and low ESL MLCCs covering high frequency noise suppression  Please contact NIC for evaluation samples and to review your requirements Page 2
