ECMF4-20A42N10中文资料ESD保护共模滤波器数据手册ST规格书

描述 Description

This device is a highly integrated common mode filter designed to suppress EMI/RFI common mode noise on high speed differential serial buses like HDMI 2.0, HDMI1.4, USB 3.1 Gen 1, Ethernet, MIPI, Display Port and other high speed serial interfaces. It has a very large differential bandwidth to comply with these standards and can also protect and filter 2 differential lanes.

特性 Features

• 5GHz differential bandwidth to comply with HDMI 2.0, HDMI 1.4, USB 3.1, MIPI, Display Port, etc.
• High common mode attenuation on LTE, GSM, GPS and WLAN frequencies:
•-13 dB at 0.7 GHz
•-23 dB at 1.5 GHz
•-25 dB at 2.4 GHz
•-23 dB at 2.7 GHz
•-13 dB at 5.0 GHz
• Very low PCB space consumption
• Thin package: 0.5 mm max
• Lead free and RoHS package
• High reduction of parasitic elements through integration

简介

ECMF4-20A42N10属于滤波器的共模扼流圈。由ST制造生产的ECMF4-20A42N10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。
