EMI Cores ESD-FPL Series Solid Cores for Flat Cables for High Frequency (Bare) Overview Applications The KEMET ESD-FPL Series solid cores are designed for use on flat cables. A wide range of Nickel Zinc (NiZn) options are available in bare type and allows for targeting of specific high frequency ranges. EMI cores are part of a family of passive components which address the issues of noise or electromagnetic interference (EMI) in circuits or systems.
EMI Core – ESD-FPL Series Solid Cores for Flat Cables for High Frequency (Bare) Part Number System ESD- FPL- 14.5- 3 Series Form Type Core Size Outer Length Code (mm) Core Size Thickness (mm) ESD- Solid See Table 1 See Table 1 Core Material and Effective Frequency Range There are two ferrite material options for KEMET EMI Cores: Nickel-Zinc (NiZn) and Manganese Zinc (MnZn). Each core material has a different resistance and effective frequency range.
EMI Core – ESD-FPL Series Solid Cores for Flat Cables for High Frequency (Bare) 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.

EMI Core – ESD-FPL Series Solid Cores for Flat Cables for High Frequency (Bare) Handling Precautions EMI Cores should be stored in normal working environments. While the EMI Cores themselves are quite robust in other environments, avoid exposure to high temperatures, high humidity, corrosive atmospheres and long term storage for case, snap-on and split types. KEMET recommends that maximum storage temperature not exceed 40°C and maximum storage humidity not exceed 75% relative humidity.
