Abstract
An electrical component includes a plurality of laminated layers 34, 44, 53, 64, of ferrite material, each layer having a conductive coil 40, 50, 58, 70 printed thereon. The conductive coil is formed by first printing a conductive sheet material 36, 48, 56, 68 on top of the ferrite layer, and then by exposing the conductive sheet material to a burst of laser energy focused in a predetermined pattern which cuts the coil out of the conductive sheet member.
