TDK MCZ1210AH Common Mode Filters are designed for use in high-speed differential signal line applications. These compact multilayer common mode filters operate in a wide frequency range for differential mode transmission ensuring common mode impedance. The MCZ1210AH filter's common mode noise is suppressed with nearly no effect on the high-speed differential transmission line. Typical applications include electronic equipment with a high-speed interface, mobile phones, PCs, portable game machines, DVD players, TVs, and mobile audio.
