CSPEMI202AG
2 Channel Headset
Microphone EMI Filter with
ESD Protection
Product Description
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 35 dB 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.
In addition, the CSPEMI202AG provides a very high level of
protection for sensitive electronic components that may be subjected

to electrostatic discharge (ESD). The diodes safely dissipate ESD
strikes of ± 8 kV, the maximum requirement of the IEC 61000 ? 4 ? 2
international standard. Using the MIL ? STD ? 883 (Method 3015)
specification for Human Body Model (HBM) ESD, the device
provides protection for contact discharges to greater than ± 15 kV.
The CSPEMI202AG is particularly well ? suited for portable
electronics (e.g. cellular telephones, PDAs, notebook computers)
because of its small package format and low weight. The
CSPEMI202AG is available in a space ? saving, low ? profile Chip
