CM1402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 CM1402 is an EMI filter array with ESD protection, which integrates three pi filters (C-R-C) and two additional channels of ESD protection. The CM1402 has component values of 20pF-47Ω-20pF, and 20pF-100Ω-20pF. 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 diodes connected to the filter ports are designed and characterized to safely dissipate ESD strikes of ±10 kV, beyond the maximum requirement of the IEC 61000-4-2 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 ±25 kV.

特性 Features

• Three channels of EMI filtering, each with ESD protection

• Protects Vcc
• Greater than 30 dB of attenuation at 1 GHz
• Important for RF noise suppression
• Chip Scale Package features extremely low lead inductance for optimum filter and ESD performance
• I/O port protection for mobile handsets, notebook computers, PDAs, etc.

应用 Application

• SIM Card slot in mobile handsets
• EMI filtering for data ports in cell phones, PDAs or notebook computers
• Mobile Devices

简介

CM1402属于滤波器的EMI/RFI滤波器（LCRC网络）。由制造生产的CM1402EMI/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。
