Round cable snap-it assemblies 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 31, 43 and 46 material cores are performed on the E4991A/HP4291B Impedance Analyzer. The 61 material parts are tested on the E4991A / HP4291B Impedance Analyzer and 75 material parts are tested on the E4990A Impedance Analyzer. Cores are tested with the shortest practical wire length.
| Typical Impendance (Ω) | |
| 25 MHz+ | 82 |
| 100 MHz+ | 130 |
A NiZn ferrite developed to combine a high suppression performance, from 30 MHz to 500 MHz, with a very high DC resistivity.
