CM1411-03CP濾波器的EMI/RFI濾波器（LCRC網絡）規(guī)格書PDF中文資料

CM1411-03CP屬于濾波器的EMI/RFI濾波器（LCRC網絡）。由安森美半導體公司制造生產的CM1411-03CPEMI/RFI 濾波器（LC，RC 網絡）該系列產品將幾種無源元器件集成到單個裝置中，可用于產生電流的頻率依賴性阻抗。盡管有其他類型，但大多數都是用于抑制不必要高頻信號傳輸的低通型，否則可能會導致干擾或意外操作。

Product Description

The CM1411 is a dual, low-pass filter array integrating two pi-style filters (C-R-C) that reduce EMI/RFI emissions while providing ESD protection. This part is custom-designed to interface with a speaker port on a cellular telephone or similar device. Each high quality filter provides more than 35dB attenuation in the 800 to 2700 MHz range. These pi style filters support bidirectional filtering that control EMI both to and from a speaker element. They also support AC signals with a cutoff frequency of 31MHz, enabling audio signals to pass through without distortion.
