• The column "H (Oe)" gives for each bead the calculated dc bias field in oersted for 1 turn and 1 ampere direct current. 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.

Suppression beads are controlled for impedances only. Minimum impedance values are specified for the + marked frequencies. The minimum impedance is typically the listed impedance less 20%.
Single turn impedance tests for 73 and 43 material beads are performed on the E4990A Impedance Analyzer. The 15, 20 and 61 material beads are tested on the E4991A / HP4291B Impedance Analyzer. Beads are tested with the shortest practical wire length.

| 250 MHz | 39 |
A new high permeability NiZn material developed for suppression and broadband applications. This material with its higher permeability than many other NiZn types provides high impedance levels extending down to 10 MHz. Optimal suppression frequency is 10-250 MHz.
