EMI Cores ESD-R Toroidal Cores for Round Cables for Low & High Frequency (Bare, coated & with case) Overview Applications The KEMET ESD-R series solid toroidal cores are designed to use on round cables. The wide range of Manganese Zinc (MnZn) and Nickel Zinc (NiZn) options are available in bare, coated, and case types and allows for targeting of specific frequency ranges.
EMI Core – ESD-R Toroidal Cores for Round Cables for Low & High Frequency (Bare, coated & with case) Part Number System ESD- R- 10 D Series Shape Type Core Size Outer Dimension Code (mm) Internal Management Code ESD- Ring See Table 1 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.
EMI Core – ESD-R Toroidal Cores for Round Cables for Low & High Frequency (Bare, coated & with 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.
