ECMF04-4HSWM10中文资料高速串行接口的ESD保护共模滤波器数据手册ST规格书

描述 Description

The ECMF04-4HSWM10 is a highly integrated common mode filter designed to suppress EMI/RFI common mode noise on high speed differential serial buses like HDMI Full HD, MIPI, Display Port and other high speed serial interfaces.

The device has a very large differential bandwidth to comply with these standards and can protect and filter two differential lanes.

特性 Features

• Very large differential bandwidth to comply with HDMI Full HD, MIPI, USB2.0, USB3.2 Gen 1, Display Port and other high speed serial interfaces
• High common mode attenuation on WLAN frequencies:
•28 dB at 2.4 GHz and -16 dB at 5.0 GHz
• Very good attenuation at LTE, GSM and GPS frequencies
• Large bandwidth: 4.2 GHz
• Low PCB space consumption
• Thin package for compact applications: 0.55 mm max.
• High reduction of parasitic elements through integration
• RoHS package
• IEC 61000-4-2, level 4:
•±15 kV (air discharge)
•±8 kV (contact discharge)

简介

ECMF04-4HSWM10属于滤波器的共模扼流圈。由ST制造生产的ECMF04-4HSWM10共模扼流圈共模扼流圈是一种电气滤波器，能阻止两条或更多条数据或电源线共有的高频噪声，但允许期望的直流或低频信号通过。共模 (CM) 噪声电流通常来自无用的无线电信号、非屏蔽电子设备、逆变器和电机等来源。如果不加以过滤，这种噪声会在电子设备和电路中带来干扰问题。
