Signal Integrity Solutions - Ferrite EMI Chip Beads
EMI and electrical noise can originate at, or affect, almost any device on a circuit board. Ferrite chip beads provide the most widely used, cost effective, compact EMI filtering option for circuit designers. Ferrite beads provide lossy impedance at a variety of impedance and frequency ranges. Compact package sizes, as small as EIA 0402, assist dense circuit board construction and allow the ferrite chip beads to be placed close to the EMI source or receptor.
Impedance ratings (at 100 MHz) above 2500 Ohms, with even higher peak frequencies, reduce maximum EMI. High frequency versions, with peak impedance above 3GHz, address the highest-speed systems. Version capable of carrying 10 Amps continuous current suit the most demanding power circuits.
