CMD offers both L-C and R-C filters designed to minimized EMI on high-speed buses found in digital cameras and LCD displays. With increasing data rates, EMI issues have become even more paramount in the effort to ensure reliable product performance. With the introduction of EMI filters with integrated inductors, CMD has met the challenge by providing high-performance filtering all on one substrate.
