The 742730022 is a 4-way multiline EMI suppression Ferrite Bead offers high impedance common-mode inductor with 2x2 windings made by PCB line connection. With the appropriate layout the impedance (i.e. 4 windings) respectively the current (parallel circuit) could be increased. The WE-MLS series ferrite bead is suitable for absorption of common or differential mode interferences in the field of EMC. It is also ideal for high-current DC output filters of power supplies battery chargers, industrial power supplies, multi-conductor systems and power electronics, filtering components of low voltage power supplies and 4-line sensor applications.
