CSPEMI307A中文资料EMI Filter with ESD Protection数据手册ONSEMI规格书

描述 Description

The CSPEMI307A is a multichannel EMI/ESD array offering a combination of four low-pass filter + ESD channels to reduce EMI/RFI emissions on a data port and four dedicated ESD-only channels intended specifically for ESD protection on a USB port. Each EMI/RFI channel integrates a high quality pi-style filter (C-R-C) which provides greater than 30dB attenuation in the 800-2700 MHz range. These pistyle filters support bidirectional filtering, controlling EMI both to and from a data port connector.

特性 Features

EMI/ESD channels provide greater than 32dB attenuation at 1GHz
Chip Scale Package features extremely low lead inductance for optimum filter and ESD performance
Four channels of combined EMI/RFI filtering + ESD protection
Four additional channels of ESD-only protection

应用 Application

EMI filtering and ESD protection for both data and I/O portsOuter 4 channels provide ESD protection for USB lines and other I/O port applications
Wireless Handsets, Handheld PCs / PDAs, MP3 Players, Notebooks, Desktop PCs

简介

CSPEMI307A属于滤波器的EMI/RFI滤波器（LCRC网络）。由ONSEMI制造生产的CSPEMI307AEMI/RFI 滤波器（LC，RC 网络）该系列产品将几种无源元器件集成到单个装置中，可用于产生电流的频率依赖性阻抗。尽管有其他类型，但大多数都是用于抑制不必要高频信号传输的低通型，否则可能会导致干扰或意外操作。
