Product Overview
CSPEMI202A: EMI Filter with ESD Protection, Headset Microphone
For complete documentation, see the data sheet.
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 Benefits

provides ESD protection in a monolythic Chip Scale Package
• Extremely low lead inductance for optimum filter and ESD
performance
• Using Chip Scale Packaging to eliminate the long wires
associated
• Cellular phones, notebook computers, netbook computers,
portable navigation devices
Applications
• Audio interfaces on wireless devices
