LF Low Frequency28 Broadband High Performance HF High Frequency > ) Ω Select the appropriate ferrite material for the EMI frequency range to be attenuated (refer to cable core material impedance vs. frequency chart above). ׷ Ferrite material composition affects core performance most. High performance material is best. Cheap, low performance materials require the use of larger, heavier cores. Use high performance ferrite material and select the smallest core that will do the job. High performance material allows the use of smaller, lighter and lower cost cores. Shape (design) and mass of the...
