Product Overview
CSPEMI201A: EMI Filter with ESD Protection, Headset Speaker
For complete documentation, see the data sheet
Product Description
The CSPEMI201AG is a dual low-pass filter array integrating two pi-style filters (C-R-C) that reduce EMI/RFI emissions while at the
same time 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 800-2700 MHz range. These pi-style filters support
bidirectional filtering, controlling EMI both to and from a speaker element. They also support bipolar signals with a cutoff frequency of
31MHz, enabling audio signals to pass through without distortion.
Features
