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 pi-style 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 61000-4-2 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 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.
