Abstract: Multilayer inductors (MLI, MLH) - Rods (ROD) - SMD beads (BDS) - SMD common mode chokes (CMS) - SMD , products are recommended for new designs. Preferred These products are recommended for use in current , temperature, called the Curie Temperature (TC). They can easily be magnetized and have a rather high intrinsic resistivity. These materials can be used up to very high frequencies without laminating, as is , requires sintering to obtain the final ferrite properties. NiZn ferrites have a very high resistivity ...
