Product Description
The CM1683 is an L-C EMI filter array with ESD protection, which integrates two Pi-filters (C-L-C) for the headset speaker. The CM1683 has component values of 100pF-3nH-100pF. The parts include ESD protection diodes on all input/output pins, which provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The ESD diodes connected to the filter ports safely dissipate ESD strikes of ±8kV, beyond the maximum requirement of the IEC61000-4-2 international standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the pins are protected for contact discharges at greater than ±15kV.

Features
• Two channels of EMI filtering

• Greater than -40dB of attenuation at 1GHz
• 8-lead, 2.00mm x 2.00mm, 0.5mm pitch uDFN package
• 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
