Ferrite composition and electronic device

摘要

The present invention relates to a ferrite composition that, in low-temperature sintering, has a high Q-value even in high magnetic field of scores to hundreds A/m, and a low rate of Q-value reduction even if the magnetic field is increased, and provides an electronic device with a pellet consisting of the ferrite composition. The main component is comprised of 25.0-49.8 mol% iron oxide in terms of Fe2O3, 5.0-14.0 mol% copper oxide in terms of CuO, 0-40.0 mol% zinc oxide in terms of ZnO, and a remaining part of nickel oxide. The sub component includes 0.2-5.0 wt% silicon oxide in terms of SiO_2, 0.10-3.00 wt% bismuth oxide in terms of Bi_2O_3, and 0.10-3.00 wt% cobalt oxide in terms of Co_3O_4, with respect to the main component.
