#FERRITE CORE INDUCTOR DIGIKEY PORTABLE#

The compact power multilayer inductors in 1008 package (2.5 mm x 2.0 mm x 1.0 mm) not only offer high rated currents (up to 2.4 A), but also a lower DCR than comparable to standard multilayer inductors types. The dimensions of the storage chokes required can therefore be reduced by up to 90%. Switching controllers like the Micrel MIC2285 already work with 4 MHz. In order to allow minimization of the coil volume, the switching controller IC is driven at ever-higher switching frequencies. This is where the power multilayer types apply. Wired components are out of the question in these orders of magnitude.

The miniaturization of SMD components, especially inductors, is a widespread trend in portable devices, as it is especially storage chokes that frequently require the most space. 2.34: Power Multilayer Inductors image source: WГјrth Elektronik WE-PMI

Low DC resistance, therefore also suitable for low-voltage systemsДЇig.

Do not operate in the self-resonant range.

This component is especially suitable as an inductor in filters and resonant circuits where low interference from external signals is required and in circuits with high packing density.

The multilayer inductor may be seen as a вЂњcompromiseвЂќ between the ceramic inductor and SMD ferrite.

The ferrite body magnetically shields the component, significantly reducing external interference and cross-talk. 2.33: Structural schematics of multilayer SMD inductors 2.32: SMD-Multilayer inductor image source: WГјrth Elektronik WE-MIДЇig. If the wire windings on the outside of a conventional вЂњcoilвЂќ are mounted inside the coil body, the so-called multilayer SMD inductor (Figure 2.32) is created.ДЇig.
