43 SPLIT FLAT CABLE CORE
Explanation of Part Numbers:
– Digits 1 & 2 = Product Class
– Digits 3 & 4 = Material Grade
Flat cable suppression core can accommodate multi-conductors flat cables, in widths from 12.7 mm (0.500) up to 77 mm (3.0). These flat cable cores are available in two ferrite material grades to reduce conducted EMI from 1 MHz to hundreds of MHz.
Our Expanded Cable & Suppressor Kit (part number 0199000005) contains a selection of these flat cable cores and clips.
Flat Cable Cores are available in selected sizes in the Flex Circuit & Ribbon Cable Core Kit (part number 0199000038).
Assembly clips are available for most of the split flat cable cores. See section Flat Cable Cores Assembly clips.

| 100 MHz+ | 192 |
| 250 MHz | 258 |
Flat cable suppression cores, split or single cores, are controlled for impedances only. Minimum impedance values are specified for the + marked frequencies. The minimum impedance is typically the listed impedance less 20%.
Centered, single turn impedance tests for the 31 and 43 material parts are performed on the E4990A Impedance Analyzer. All tests are made with the shortest practical wire length.
| Typical Impendance (Ω) | |
| 10 MHz | 57 |
| 25 MHz+ | 100 |
| 100 MHz+ | 188 |
| 250 MHz | 295 |
