Ferrocore DE0703-18 is a ferrite core that is used in a variety of electronic applications, such as inductors, transformers, and EMC/EMI interference suppression. This core is made of nickel-zinc soft Ferrite, which typically offers the highest relative permeability of popular ferrites. It is widely used in industrial and automotive applications, such as dc-to-dc converters, inverters, motor drives and power supplies. This core has a tolerance of +25/-20% and can be delivered in a variety of shapes including small toroids, E and I laminations, square, and bar. It is available with a core within a shell or stand-alone.
