CM1410 4 Channel Headset EMI Filter with ESD Protection Features 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. • • • • • • • • • • • 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 Applications • • • • • • • EMI filtering and ESD protection for audio ports Wireless Handsets Handheld PCs / PDAs MP3 Players Digital Camcorders Notebooks Desktop PCs In addition, the CM1410 provides a very high level of protection for sensitive electronic components that may be subject to electrostatic discharge (ESD). The CM1410 can safely dissipate ESD strikes of +8kV, 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 +15kV. The CM1410 also includes a single channel of ESD-only protection. The CM1410 is particularly well suited for portable electronics (e.g., cellular telephones, PDAs, notebook computers) because of its small package format and low weight. The CM1410 incorporates Optiguard™ coating which results in improved reliability at assembly.The CM1410 is available in a space-saving, low-profile Chip Scale Package with optional lead-free finishing.
