Product Description
The CSPEMI201AG is a dual lowïpass filter array integrating two
piïstyle filters (CïRïC) that reduce EMI/RFI emissions while at the
same time providing ESD protection. This part is customïdesigned 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
800ï2700 MHz range. These piïstyle 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
61000ï4ï2 international standard. Using the MILïSTDï883 (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 wellïsuited for portable
electronics (e.g. cellular telephones, PDAs, notebook computers)
because of its small package and low weight. The CSPEMI201AG is
available in a spaceïsaving, lowïprofile Chip Scale Package with
RoHS compliant leadïfree finishing.
