We manufacture both surface mount and leaded ferrite beads in multilayer and pressed construction. Our surface mount designs come in a wide variety of types such as standard, mid current, high current, ultra high current and high frequency. We even offer bead arrays with our MLBA20 series. Sizes include 0402, 0603, 0805, 1206, 1806 and 1812. Our WFB series of wide band chokes are perfect for EMI and RFI solutions. Values range from 5 ohms up to 2700 ohms.
