PCMF1USB3S滤波器的共模扼流圈规格书PDF中文资料

1. General description

Common-mode ElectroMagnetic Interference (EMI) filters with integrated ElectroStatic Discharge

(ESD) protection for one, two and three differential channels. The devices are designed to provide

low insertion loss for differential high-speed signals on each channel while unwanted commonmode

signals are attenuated.

Each differential channel incorporates two signal lines that are coupled by integrated coils. Diodes

provide protection to downstream components from ESD voltages up to ±15 kV on each signal line.
