ECMF系列保护器件(IPAD)

意法半导体的ECMF系列提供了业内首款具有高效ESD保护功能的硅共模滤波器。该系列产品现在采用micro-QFN和CSP封装,实现了超小巧的外形,符合高速串行接口标准的要求,例如USB、MIPI、MDDI或HDMI。

ECMF器件旨在提高手机、笔记本电脑和平板电脑等应用的抗扰性,保护它们免遭破坏性ESD空气和接触放电的损害。

该ECMF系列具有以下特性:

  • 超大差分带宽:高达7 GHz
  • 高共模衰变:从800 MHz到2.5 GHz
  • 符合IEC 61000-4-2 4级ESD标准的要求
  • 稳定的ESD保护,实现了低残余峰值电压(VPEAK < 50 V)USB
  • 超小型和简单的流通布局
  • 适于MIPI D-PHY、USB 2.0和HDMI应用

 

The most integrated ECMF™ for USB 2.0 high-speed lines

The ECMF02-3F3 – intended for USB 2.0 high-speed lines – combines 3 ESD protection diodes with a common-mode filter within a tiny 1.1 mm², 0.5-mm thick, chip-scale package with 0.4-mm pitch bumps. It saves 52% PCB area compared to an equivalent discrete solution, and targets all low profile applications. Its ESD protection, up to 8 kV contact, IEC 61000-4-2 Level 4 compliant, makes it ideal for USB 2.0 connectors in electronic gadgets requiring robust ESD protection but high signal integrity. In addition, its DC resistance of less than 4.5 Ω makes it compliant with USB 2.0 HS TDR requirements.
