FAIR-RITE0331184751Ferrite Core
The Fair-Rite Oval Clip-It 31 material assemblies are controlled for impedances only. Minimum impedance values are specified for the positive marked frequencies. The minimum impedance is typically the listed impedance less 20%.
Single-turn impedance tests for 31, 43 and 46 material cores are performed on the E4991A or HP4291B impedance analyzer
61 material parts are tested on the E4991A or HP4291B impedance analyzer
75 material parts are tested on the E4990A impedance analyzer
Cores are tested with the shortest practical wire length
