A Gigaspira Bead is a chip bead that decreases stray capacitance more than standard chip beads by changing internal structures and has extended the SRF to the high-frequency side.
Because it can remove noise at higher-frequency bands, it can be used alone for high-frequency and broadband noise, without the need for two chips.
