EMI Core – ESD-SR-H/HL Snap-on Cores for Round Cables for High Frequency (with High Heat Resistance & Cable Holding Mechanism case) Turns and Impedance Characteristics Figure 1 – How to count turns When the desired performance of an EMI core cannot be obtained with a single pass through the core, the impedance characteristics can be changed with multiple turns. A turn is counted by the number of lead-wire windings which pass through the inner hole of the core.

EMI Core – ESD-SR-H/HL Snap-on Cores for Round Cables for High Frequency (with High Heat Resistance & Cable Holding Mechanism case) Magnetic Permeability of Ferrite Material In order to achieve most efficient noise reduction, it is important to select the material according to the target frequency band. Depending on its magnetic permeability, a particular ferrite material will be effective in a certain frequency band.
