com 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.
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.
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...
