Six Hole Choke
Ferronics offers a line of six hole beads and chokes for applications where a single hole bead does not provide the impedance level desired. Six hole beads are provided in the following materials: J (850 ui for 20 – 300 MHZ) & K (125ui for 50 – 500 MHz). The standard chokes are offered in 1.5, 2.5 and 3 turn versions (Figures 1, 2 and 4). Ferronics also offers a common mode choke version with 2 x 1.5 turns (Figure 3). The six hole bead can be custom wound to meet your particular requirements. Custom configurations (ie. material, shape, holes, turns, etc.) available upon request.
