Product Description
The CSPEMI205G is a lowïpass filter array integrating three
piïstyle filters (CïRïC) that reduce EMI/RFI emissions while at the
same time providing ESD protection. This part is customïdesigned to
interface with the headset port on a cellular telephone, and contains
two different filter values. Each high quality filter provides more than
30 dB attenuation in the 800ï2700 MHz range. These piïstyle filters
support bidirectional filtering, controlling EMI both to and from the
microphone and speaker elements. They also support bipolar signals,
enabling audio signals to pass through without distortion.
In addition, the CSPEMI205G provides a very high level of
protection for sensitive electronic components that may be subject to
electrostatic discharge (ESD). The input pins 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 CSPEMI205G is particularly wellïsuited for portable
electronics (e.g. cellular telephones, PDAs, notebook computers)
because of its small package format and low weight. The
CSPEMI205G is available in a spaceïsaving, lowïprofile Chip Scale
Package with RoHS compliant leadïfree finishing.
