CM1412中文资料EMI Filter with ESD Protection, 2-Channel数据手册ONSEMI规格书

描述 Description

The CM1412 is a dual, low pass filter arrayr integrating two pi-style filters (C-R-C) that reduce EMI/RFI emissions while providing ESD protection. This part is custom-designed to interface with a microphone port on a cellular telephon or similar device. Each high quality filter provides more than 35 dB attenuation in the 800 to 2700 MHz range. These pi stlye filters support bidirectional filtering that can address both EMI and ESD from and to the device. They also support AC signals, enabling audio signals to pass through without distortion.

特性 Features

• Pi-style EMI filters in a capacitor-resistor-capacitor(C-R-C) network
• Greater than 40dB attenuation at 1GHz
• Extremely low lead inductance for optimum filterand ESD performance

应用 Application

EMI filtering and ESD protection for headset/speaker ports

简介

CM1412属于滤波器的EMI/RFI滤波器（LCRC网络）。由制造生产的CM1412EMI/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。
