| CM1411 2 Channel Headset/Speaker EMI Filter with ESD Protection Features * * * * * * * * * * * * Functionally and pin compatible with CMD's CSPEMI201A OptiGuardTM coated for improved reliability at assembly Two channels of EMI filtering Pi-style EMI filters in a capacitor-resistor-capacitor (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 version available 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 at the same time 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 800-2700 MHz range. These pi-style filters support bidirectional filtering, controlling 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 OptiGuardTM coating which results in improved reliability at assembly and is available in a space-saving, low-profile Chip Scale Package with optional lead-free finishing.
