ECMF02-2BF3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 ECMF02-2BF3 is a highly integrated common mode filter designed to suppress EMI/RFI common mode noise on high speed differential serial buses like MIPI D-PHY, MDDI, USB 2.0 and HDMI.

The ECMF02-2BF3 can protect and filter one differential lane.

特性 Features

• Very large differential bandwidth above 5 GHz
•- 23 dB at 900 MHz.
•- 20 dB between 800 MHz and 2.2 GHz.
• Thin package: 0.50 mm max. after reflow
• High reduction of parasitic elements through integration
•IEC 61000-4-2 level 4 input and output pins:
• ±15 kV (air discharge)
• ±8 kV (contact discharge)

简介

ECMF02-2BF3属于滤波器的共模扼流圈。由ST制造生产的ECMF02-2BF3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。
