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-2Ω-
117pF. 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 MIL-
STD-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.
