CM1411

2-Channel Headset/Speaker EMI Filter Array with ESD Protection CM1411 Features • • • • • • • • • • • • Functionally and pin compatible with the CSPEMI201A OptiGuard™ coated for improved reliability at assembly 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 in each channel (HBM) Supports AC signals—ideal for audio applications Extremely low lead inductance for optimum filter and ESD performance 5-bump, 0.950mm X 1.410mm footprint Chip Scale Package (CSP) Lead-free RoHS compliant Product Description The CM1411 is a dual, low-pass filter array integrating two pi-style filters (C-R-C) that reduce EMI/RFI emissions while providing ESD protection. This part is custom-designed to interface with a speaker port on a cellular telephone or similar device. Each high quality filter provides more than 35dB attenuation in the 800 to 2700 MHz range. These pistyle filters support bidirectional filtering that control EMI both to and from a speaker element. They also support AC signals with a cutoff frequency of 31MHz, enabling audio signals to pass through without distortion. In addition, the CM1411 provides a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The CM1411 can safely dissipate ESD strikes of +8kV, the maximum requirement of the IEC 61000-42 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 CM1411 is particularly well-suited for portable electronics (e.g., cellular telephones, PDAs, notebook computers) because of its small package format and low weight. The CM1411 incorporates OptiGuard™ coating which results in improved reliability at assembly and is available in a space-saving, lowprofile Chip Scale Package with lead-free finishing.
