CSPEMI205中文资料EMI Filter with ESD Protection, Single Mic / Stereo Speaker数据手册ONSEMI规格书

描述 Description

The CSPEMI205G is a low-pass filter array integrating three pi-style filters (C-R-C) that reduce EMI/RFI emissions while at the same time providing ESD protection. This device is custom-designed to interface with the headset port on a cellular telephone, and contains two different filter values. Each high quality filter provides more than 30dB attenuation in the 800-2700 MHz range. These pistyle filters support bidirectional filtering, controlling EMI both to and from the microphone and speaker elements. They also support bipolar signals, enabling audio signals to pass through without distortion.

特性 Features

• Integrated microphone and speaker EMI suppression and ESD protection
• Bi-directional diodes protects equally in both directions
• Extremely low lead inductance for optimum filter and ESD performance

应用 Application

• External speaker and microphone ports on wireless handsets

简介

CSPEMI205属于滤波器的EMI/RFI滤波器（LCRC网络）。由ONSEMI制造生产的CSPEMI205EMI/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。
