Electromagnetic Interference (EMI) greatly influences the operation of electronic devices; either by the fact that the fault is generated or received them from the environment through the device itself. Ferrites exhibit excellent EMI shielding protection against common-mode and differential Conducted interference since their damping properties are proportional to the frequency. This experienced the low-frequency signals no attenuation, while high-frequency interference can be effectively suppressed.
The materials are suitable, for example, for bar-cores, toroidal cores, cable shields, all kinds of inductors, EMI and SMD beads.
