LTCC white paper
There is a growing need for transformers that are low-cost, small, low-profile, and surface-mountable. In addition, they must meet safety requirements while maintaining transformer efficiency. This paper discusses an approach geared to meet these requirements. It involves parallel LTCC processing of ferrite tape and low temperature (850-950° C) co-firing of the screen printed silver primary and secondary coils resulting in a small, low-profile, highly reliable product.

Low-Temp Co-Fired Magnetic Tape Yields High Benefits
This article--originally published in the Jan. 1, 2003 issue of Power Electronics Technology, was written by George Slama, who is now part of the NASCENTechnology team. According to Slama, low-temperature co-fired ceramic (LTCC) ferrite, combined with screen-printable silver conductor and low-permeability dielectric produce small, low power, low profile transformers with no wire or discrete core.
