CSPEMI202A中文资料EMI Filter with ESD Protection, Headset Microphone数据手册ONSEMI规格书

描述 Description

The CSPEMI202AG is a dual low-pass filter array integrating two pi-style filters (C-R-C) that reduce EMI/RFI emissions while at the same time providing ESD protection. This part is custom designed to interface with a microphone port on a cellular telephone or similar device. Each high quality filter provides more than 35dB attenuation in the 800-2700 MHz range. These pi-style filters support bidirectional filtering, controlling EMI both to and from a microphone element. They also support bipolar signals, enabling audio signals to pass through without distortion.

特性 Features

Extremely low lead inductance for optimum filter and ESD performance
Using Chip Scale Packaging to eliminate the long wires associated
Cellular phones, notebook computers, netbook computers, portable navigation devices

应用 Application

Audio interfaces on wireless devices

简介

CSPEMI202A属于滤波器的EMI/RFI滤波器（LCRC网络）。由ONSEMI制造生产的CSPEMI202AEMI/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。
