FERRITE INJECTION MOULDING “FIM”
Our Classic Material Fi311s:
A medium permeable MnZn-Ferrite for free shaping. For use in sensors or niche
markets with nearly the same magnetic behaviour as standard ferrite cores.
Development of an injection
moulded ferrite for:
Free shaping
High permeability
Low losses
Improved cooling
Integration of functions
