CM1443-04数据手册滤波器的EMI/RFI滤波器（LCRC网络）规格书PDF

描述 Description

The CM1443 is a fourchannel low-pass EMI filter array with ESD protection that reduces EMI/RFI emissions while providing robust protection from ESD strikes. Each EMI filter channel integrates a high quality pi-style filter (8.5pF-100 Ohm-8.5pF) which provides greater than 30dB of attenuation in the 800MHz to 2.7GHz frequency range. The parts include avalanche-type ESD diodes on every pin, which provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The ESD protection diodes connected to the filter ports safely dissipate ESD strikes of ±15kV, beyond the maximum requirement of the IEC61000-4-2 international standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the pins are protected for contact discharges at greater than ±30kV.

特性 Features

• Excellent attenuation of noise in the wireless carrier bands
• Supports clocks frequencies up to 24 MHz
• ±15kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge)

应用 Application

• Cellular Phones, Smart Phones,Netbooks, Notebooks, Portable Navigation Devices

简介

CM1443-04属于滤波器的EMI/RFI滤波器（LCRC网络）。由制造生产的CM1443-04EMI/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。
