CSPEMI205G 3-Channel Headset Microphone EMI Filter with ESD Protection Product Description The CSPEMI205G is a low−pass filter array integrating three 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 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 800−2700 MHz range. These pi−style filters .

CSPEMI205G 3-Channel Headset Microphone EMI Filter with ESD Protection Product Description The CSPEMI205G is a low−pass filter array integrating three 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 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 800−2700 MHz range. These pi−style 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 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 CSPEMI205G is particularly well−suited 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 space−saving, low−profile Chip Scale Package with RoHS compliant lead−free finishing.
