Miscellaneous Suppression Cores (2643175451)
Part Number: 2643175451
43 SPLIT SUPPRESSOR 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.

|Typical Impedance (Ω)|
These suppression cores are controlled for impedance only. The minimum impedance is listed on our catalog drawing.
Single turns tests are performed on the E4991A / HP4291B Impedance Analyzer with the shortest practical wire length.
|Typical Impendance (Ω)|
This NiZn is our most popular ferrite for suppression of conducted EMI from 20 MHz to 250 MHz. This material is also used for inductive applications such as high frequency common-mode chokes.
