4-Channel LCD and Camera EMI Filter Array with ESD Protection

CM1436-04DE
4-Channel EMI Filter Arrays
with ESD Protection
Product Description
The CM1436 is an EMI filter array with ESD protection, which
integrates four pi filters (C−R−C). Each CM1436 filter has component
values of 15 pF − 200 W − 15 pF. These parts include ESD protection
diodes on every pin, providing 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 15 kV contact discharge, twice the
specification requirement of the IEC 61000−4−2, Level 4 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 30 kV.
This device is particularly 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
CM1436 is ideal for EMI filtering and protecting data lines from ESD
in wireless handsets.
The CM1436 is available in space−saving, low−profile, 8−lead
0.4 mm pitch WDFN packages. It is fabricated with the Centuriont
process and available with lead−free finishing.
