Abstract
PURPOSE:To reduce the height of package and to improve mass productivity, by packing a ceramic substrate having primary and secondary windings formed into spiral-like films on the surface thereof through utilization of a core made of low temperature fired magnetic material. CONSTITUTION:Primary and secondary windings 12-1, 12-2 having film patterns are formed spirally onto the surface of a thin square ceramic substrate 10 having a through-hole 11 in the center. A through-hole 14 is made through ends of windings 13-1b, 13-2b, and lead-out patterns 15-1, 15-2 communicated with the side edge of the substrate 10 are provided. Z-shaped terminals are brazed to the ends of windings 13-1a, 13-2a, and a pair of starting side terminals 16-1a, 16-2a are secured to the side edge of the substrate 10. Then the substrate 10 is packed into a thin board through utilization of a core 20 made of low temperature fired magnetic material. Consequently, the height of package is lowered resulting in improvement of mass productivity.
