CSPEMI201AG
2 Channel Headset Speaker
EMI Filter with ESD
Protection
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 35 dB 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 31 MHz,
enabling audio signals to pass through without distortion.
In addition, the CSPEMI201AG provides a very high level of
protection for sensitive electronic components that may be subjected
to electrostatic discharge (ESD). The CSPEMI201AG can 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 CSPEMI201AG is particularly well−suited for portable
electronics (e.g. cellular telephones, PDAs, notebook computers)
because of its small package and low weight. The CSPEMI201AG is
available in a space−saving, low−profile Chip Scale Package with
RoHS compliant lead−free finishing.
