TDK-EPC MLZ2012-H ferrite coils

TDK-EPC has developed a multilayer ferrite coil (MLZ2012-H series) in case size EIA 2012 with a rated current that is claimed to be 2.5 times higher than existing products.

With a current capability of up to 700 mA at 1.0 µH, the series is suitable for decoupling in compact electronic devices such as notebook computers and digital still and video cameras.

The improvement in the coil’s key performance was achieved using ferrite materials with an optimised multilayer structure.

This was made possible by the precise control of the enamel physical properties and allows a further improvement of the coil design and superior DC superimposition characteristics on a par with those of wire wound-type coils.

As a result, the latest series is claimed to have the highest rated current for 2012-size multilayer ferrite coils that can be used for decoupling.

The inductors are available with inductance values of 1.0 to 10 µH with a tolerance of ±20%. At DC resistance values of 0.1 to 0.68 Ω(±30%) the current range is between 200 and 700 mA.
