Product Description

The CM1436 is an EMI filter array with ESD protection, which integrates either four, six or eight pi filters (C-R-C). Each CM1436 filter has component values of 15pF-200Ω-15pF. These parts include ESD protection diodes on every pin, providing 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 safely dissipate ESD strikes of ±15kV contact discharge, twice the specification requirement of the

IEC 61000-4-2, Level 4 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.

Features

• Four, six and eight channels of EMI filtering with ESD protection

• Greater than 30dB of attenuation from 800MHz to 3GHz

• ±15kV ESD protection (IEC 61000-4-2, contact discharge)

• ±30kV ESD protection (HBM)

• Fabricated with Centurion™ advanced low capacitance zener process technology

• Space saving, low-profile 8-, 12- and 16-lead 0.4mm pitch TDFN packages

• Lead-free version available

Applications

• I/O port protection for mobile handsets, notebook computers, PDAs etc.

• EMI filtering for data ports in cell phones, PDAs or notebook computers.

• EMI filtering for LCD, camera and chip-to-chip data lines

CM1436属于滤波器 > EMI/RFI 滤波器（LC，RC 网络）。安森美半导体公司制造生产的CM1436EMI/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。
