WE-CBA SMD EMI Suppression Ferrite Beads

Würth Elektronik WE-CBA SMD EMI Suppression Ferrite Beads are AEC-Q200 qualified and can be put directly onto a printed circuit board. These ferrite beads offer excellent anti-EMI properties and low DC resistance. When placed close to the interference source (even with the smallest size of 0402), the maximal impedance at 1000Ω can be reached. Würth Elektronik WE-CBA series ferrite beads are ideal as data filters for the uncoupling of distribution voltages. Other applications include USB 2.0, control signals, RS232, RS422, DC/DC converters, and power supplies.
