Abstract

The small height inductor with a thin-film coils was designed for DC-DC converter circuit and fabricated. The thin-film coil was micro-formed on the smoothed ferrite substrate sintered at normal pressure. The size, inductance and allowable DC current of the fabricated inductor were 7.5mm×7.5mm×1.6mm (t), 23μH and 400 mA, respectively.
