Common-mode ElectroMagnetic Interference (EMI) filters with integrated ElectroStatic Discharge (ESD) protection for one, two, and three differential channels. These devices are engineered to provide low insertion loss for high-speed differential signals while attenuating unwanted common-mode signals. Each differential channel utilizes integrated coils for signal coupling and diodes for ESD protection up to 15 kV on each signal line. They offer superior common-mode suppression, excellent RF performance, and high symmetry between line pairs, making them ideal for modern high-speed interfaces.
