CM1442中文资料带 ESD 保护的 EMI 滤波器数据手册ONSEMI规格书

描述 Description

The CM1442 is a six or eight channel 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 (15pF-100 Ohm-15pF) 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

• 15kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge)
• Protects against the most agressive ESD events
• Excellent attenuation of noise in the wireless carrier bands
• SuppressedEMI assists in improving handset performance in Total Isotropic Sensitivity testing, a requirement to get agency and carrier approvals
• Supports clocks frequencies up to 24 MHz
• Offers Electro Magnetic Noise suppression with excellent signal integrity

应用 Application

• EMI filtering for data ports in cell phones, PDAs or notebook computers
• Cellular Phones, Smart Phones,Netbooks, Notebooks, Portable Navigation Devices

简介

CM1442属于滤波器的EMI/RFI滤波器（LCRC网络）。由制造生产的CM1442EMI/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。
