Headset/Speaker EMI Filter with ESD Protection CM1416 Features Product Description • The CM1416 is an EMI filter array with ESD protection, which integrates two Pi-filters (C-R-C). The CM1416 has component values of 117pF-2Ω117pF. The parts include avalanche-type ESD diodes on every pin, which provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The ESD diodes safely dissipate ESD strikes of ±30kV, exceeding the maximum requirement of the IEC 61000-4-2 international standard. Using the MILSTD-883 (Method 3015) specification for Human Body Model (HBM) ESD, these devices protect for contact discharges at greater than ±30kV. • • • • • • • • Functionally and pin compatible with the CSPEMI201A and CM1411 OptiGuard™ coated for improved reliability at assembly Two channels of EMI filtering for 8Ω speakers Pi-style EMI filters in a capacitor-resistorcapacitor (C-R-C) network Greater than 30dB attenuation at 1GHz ±30kV ESD protection on each channel per IEC 61000-4-2 Level 4, contact discharge Extremely low lead inductance for optimum filter and ESD performance 5-bump, 0.96mm X 1.33mm footprint Chip Scale Package (CSP) RoHS-compliant, lead-free finishing Applications • • • Headset Speaker port in mobile handsets I/O port protection for mobile handsets, notebook computers, PDAs etc. EMI filtering for data ports in cell phones, PDAs or notebook computers. This device is well suited for portable electronics (e.g. mobile handsets, PDAs, notebook computers) because of its small package and easy-to-use pin assignments. In particular, the CM1416 is ideal for filtering unwanted EMI-induced noise and providing ESD protection for headset speaker port applications in wireless handsets with 8Ω speakers. The CM1416 incorporates OptiGuard™ coating which results in improved reliability at assembly. The CM1416 is available in a space saving, low profile Chip Scale Package with RoHS-compliant, lead-free finishing. ©2010 SCILLC. All rights reserved.
