Abstract :
An empirical model for the low permeability LTCC magnetic material is developed based on Steinmetz equation, taking into account temperature variations and DC pre-magnetization. Steinmetz exponents and coefficient are expressed as a function of temperature and DC pre-magnetization to describe core loss for frequencies between 1 to 4 MHz, peak flux density between 5 mT to 50 mT, DC magnetic flux intensity, H, between 0 A/m to 1780 A/m and temperature range between 26degC to 70degC.
