Temperature impact on inductance and resistance values of a coreless inductor (Cu/Al2O3)

摘要

This article is devoted to the inductance and resistance evolution of a coreless inductor depending on temperature. The inductors are fabricated of thin copper films deposited on an alumina substrate and characterized up to 10 MHz with an impedance analyzer. Two types of measurements are carried out: after inductor annealing and in a thermal cycle (25-200 degrees C).
