CM1409滤波器的EMI/RFI滤波器（LCRC网络）规格书PDF中文资料

CM1409属于滤波器的EMI/RFI滤波器（LCRC网络）。由安森美半导体制造生产的CM1409EMI/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。

Product Description

The CM1409 is a family of pi-style EMI filter arrays with ESD protection, which integrates either six or eight filters (C-R-C) in a small form factor, TDFN 0.50mm pitch package. The CM1409 has component values of 15pF-100Ω-15pF per channel. The CM1409 has a cut-off frequency of 110MHz and can be used in applications with data rates up to 44Mbps. The parts include ESD diodes on every pin, which provide a very high level of protection for sensitive electronic components against electrostatic discharge (ESD).
