The KEMET ESD-FPL-21-8 is a solid core ferrite flat cable core designed for electromagnetic interference suppression. It features an inner dimension of 17mm by 0.8mm, accommodating flat cables up to 16 wires. The component utilizes nickel-zinc material and supports frequencies up to 500MHz. Its physical dimensions are 21mm in length and 8mm in height.
Verify the specific impedance value at 100MHz or other standard test frequencies against the official KEMET datasheet, as distributor listings may omit this critical parameter. Confirm that the 17mm internal width matches the target flat cable thickness precisely to ensure proper fit and magnetic coupling efficiency during installation.
Select this component when a solid core solution is required for flat cables with a maximum thickness of 0.8mm. Ensure the application frequency range aligns with the nickel-zinc material characteristics. Verify that the 21mm external length provides sufficient space within the enclosure for the targeted EMI suppression requirements.
This part belongs to the KEMET ESD-FPL series of flat cable ferrite cores. These components are engineered to suppress common-mode noise on flat ribbon cables used in digital interfaces. The series offers various internal dimensions to accommodate different cable gauges while maintaining consistent external form factors for standardized mounting.
Check for direct substitutes within the ESD-FPL series that match the 17x0.8mm internal dimensions. Alternative manufacturers offering nickel-zinc flat cable cores with identical outer dimensions and compatible frequency response should be evaluated for mechanical interchangeability.
