4 Features of NR Features The choke coil for DC/DC converters corresponding to the low profile demand in small pocket apparatus This corresponds to high current, though it is the low profile and small This series realized low DC-R and magnetically shielded construction by adopting the magnetic coat resin which has a use actual result in LB/CB series. This ferrite resin carries out the role of the ferrite ring core usually used. Structure strong against a shock-proof (free fall from 1.8m to a concrete floor) Structure comparison NR-series Competitor Drum core Magnetic resin Drum core Sleeve core Wound Wire Ag Electrode Wound Wire Flame lead Drum core + Magnetic resin Drum core + Sleeve core
