CM1411 Overview
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 35 dB attenuation in the 800 to 2700 MHz range.
CM1411 Key Features
- Functionally and Pin patible with the CSPEMI201A
