43 FULL FLAT CABLE CORE
Explanation of Part Numbers:
– Digits 1 & 2 = Product Class
– Digits 3 & 4 = Material Grade
Fair-Rite has tooled several special core geometries in the 43 & 77 material for suppression of conducted EMI.
For any non-catalog suppression core design feel free to contact our customer service or application group for feasibility and availability.
The “C” dimension, the core length, can be modified to suit specific applications.

| 100 MHz+ | 152 |
| 250 MHz | 213 |
These suppression cores are controlled for impedance only. The minimum impedance is typically the listed impedance less 20%.
Single turns tests are performed on the E4991A / HP4291B Impedance Analyzer with the shortest practical wire length.

| 10 MHz | 60 |
| 25 MHz+ | 94 |
| 100 MHz+ | 169 |
| 250 MHz | 250 |
