CSPEMI202AG

2 Channel Headset Microphone EMI Filter with ESD Protection CSPEMI202AG Features Two channels of EMI filtering Pi-style EMI filters in a capacitor-resistorcapacitor (C-R-C) network Greater than 40dB attenuation at 1GHz ±8kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge) ±15kV ESD protection on each channel (HBM) Supports bipolar signals—ideal for audio applications Chip Scale Package features extremely low lead inductance for optimum filter and ESD performance 5-bump, 0.930mm X 1.410mm footprint Chip Scale Package (CSP) RoHS compliant (lead-free) finishing www.DataSheet4U.com 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 35dB 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 ±8kV, the maximum requirement of the IEC 61000-42 international standard. Using ...
