CSPEMI202A: EMI Filter with ESD Protection, Headset Microphone

The CSPEMI202AG 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 microphone 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 microphone element. They also support bipolar signals, enabling audio signals to pass through without distortion.

Features

Two lines of EMI suppression with integrated ESD protection
Extremely low lead inductance for optimum filter and ESD performance
Cellular phones, notebook computers, netbook computers, portable navigation devices

Benefits

Suppresses noise off of strong analog and digital audio lines, provides ESD protection in a monolythic Chip Scale Package
Using Chip Scale Packaging to eliminate the long wires associated

Applications

Audio interfaces on wireless devices
