“Specifically designed for EMI suppression of high frequency circuits, the latest range of air core chip coils from Murata is fully compliant with RoHS legislation and available immediately in full production volumes. The LQW04A series provides a cost effective and miniaturised alternative to the earlier LQW15A series. Just half the volume and 60% of the mounting area, these new chip coils measure 0.8 x 0.4mm with a low 0.4mm profile, which combined with a resin-coated surface, makes them particularly suitable for high-density mounting.” Source: electronicstalk.com
