The actual dc H field in the application is this value of H times the actual NI (ampere- turn) product. For the effect of the dc bias on the impedance of the bead material, see figures 18-23 in the application note How to choose Ferrite Components for EMI Suppression. Typical Impedance () 100 MHz 35 + 250 MHz 49 + 500 MHz 65 1000 MHz 93 Electrical Properties H(Oe) 2 Suppression beads are controlled for impedances only. Minimum impedance values are specified for the + marked frequencies. The minimum impedance is listed on our catalog drawing. Catalog Drawing Single turn impedance tests for 73 and 43 material beads are performed on the E4990A Impedance Analyzer. The 61 material beads are tested on the E4991A / HP4291B Impedance Analyzer. Beads are tested with the shortest practical wire length.Single turn impedance tests for 73 and 43 material beads are performed on the E4990A Impedance Analyzer.
