Midcom's MicroMagnetics division has developed a family of transformers to demonstrate what can be done with low temperature co-fired ceramic (LTCC) transformers. Applications can be found for isolated power supplies; noise-immunity; communication interfacing; isolated data acquisition; bridging ground differences; isolated clock/sync interfaces; and process control.
The family includes a set of four transformers suitable for higher frequencies and with large turns ratios. A second set of four transformers is suitable for lower frequencies and have smaller turns ratios. Both sets have split primary and secondary windings that can be easily connected to match various circuit configurations or even to adjust the turns ratio.
The parts measure 7,6 mm square and less than 2 mm high. They are intended for low power applications and can pass as much as 1250 mW of continuous power (with 40°C rise) with a 15-24 V d.c. input. The dielectric breakdown voltage rating is 250 V r.m.s. Typical operating frequency range is 200 kHz to 1 MHz.
The rugged packaged transformers are self shielding and windings can be combined to meet specific applications. Designed for pick and place they are compatible with solder reflow.
