4 Channel Headset EMI Filter with ESD Protection
Features
Functionally and pin compatible with CSPEMI200A device Pi-style EMI filters in a capacitor-resistor-capacitor (C-R-C) network Four channels of EMI filtering with ESD protection Includes 1 channel of ESD-only protection Greater than 30dB 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 11-bump, 2.046mm X 1.436mm footprint Chip Scale Package (CSP) Optiguard™ coated for improved reliability at assembly Lead-free version available
Product Description
The CM1410 is a quad low-pass filter array integrating four pi-style filters (C-R-C) that reduce EMI/RFI emissions while at the same time providing ESD protection. This device is custom-designed to interface with the headset port on a cellular telephone, and contains 3 different filter values. Each high quality filter provides more than 20dB 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 CM1410 provides a very high level of protection for sensitive electronic ...
