This paper describes the fabrication of thin magnetic layers for an LTCC planar-type inductor with a 0.11 mm thickness. The thin ferrite layers were fabricated by tape casting method. Synthesis conditions and X-ray analysis (300 K) of the Ni0.3Zn0.62Cu0.08Fe2O4 ferrite are presented. A pure cubic, Fd 3m crystal structure was observed for the Ni0.3Zn0.62Cu0.08Fe2O4 ferrite. The complex impedance and dielectric permittivity of Ni0.3Zn0.62Cu0.08Fe2O4 ferrite were determined as a function of temperature (from −55 to 170 °C) and frequency (from 10 Hz to 2 MHz). Dc resistivity was measured in a temperature range from −55 to 170 °C. Magnetization and magnetic hysteresis were measured by a vibrating sample magnetometer (VSM) in an applied magnetic field up to 60 kOe. The inductance and quality factor were measured in a frequency range 0.1–120 MHz. With the help of finite elements method (FEM) simulation it is possible to calculate the elements electrical parameters and optimize the design. This paper presents a magnetic field modelling of an inductor structure.
