© 2017, Springer Science+Business Media, LLC, part of Springer Nature. Influence of sintering temperature on the complex permeability, the core loss density and B-H hysteresis loop of ferrite low-temperature co-fired ceramic (LTCC) multilayer toroidal cores is presented. Ferrite LTCC toroidal cores are fabricated from 22 layers of ESL 40011 tapes sintered at 885, 1000, 1100 and 1200 °C. Applying the sinusoidal excitation, the measurements are performed in the frequency range from 10 kHz to 5 MHz and for magnetic flux density from 2 to 100 mT. The measurements of sintered multilayer cores were done in order to investigate the difference in magnetic properties among those samples. This investigation enables to find optimal sintering temperature of multilayer ferrite cores which used in different multilayer magnetic component applications.
