TE Connectivity: A component that marks the end of hand-wound coils in datacom

Today, magnetic coils used for inductors and transformers are traditionally wound by people, either by hand or by winding machines that people control. Consistency varies depending on the expertise of the workers, and variations in the work force has lead to extensive product supply shortages and quality issues. As a result, the datacom industry, which has relied upon such coils for its current high-speed data products, is looking for a new coil solution that will let it advance reliably to higher, multi-gigahertz rates. Which is where the PlanarMag E2101 Ethernet single-port media filter comes in.

The E2101 is a 10/100-MHz device that, for the first time, eliminates the hand-wound coils by embedding lithographically encoiled magnetic ferrites into an FR4 substrate and enclosing it into a small surface-mount package. This filter, the first in a series of high-speed-data-communication devices, can be placed on a printed circuit board adjacent to a high-speed data interface, or even integrated into a complete RJ-45 connector. While the process by which these devices are made is similar to the way in which semiconductors are manufactured, it is a tightly kept secret, surrounded by numerous patents both granted and pending. But the proof of its effectiveness is available to anyone today in the E2101.
