CM1421
4-Channel LCD EMI Filter Array and ESD Protection Array
Product Description The CM1421 is a multichannel array consisting of four low−pass
filters with integrated ESD protection and four ESD−only protection channels designed to reduce EMI/RFI emissions on LCD data lines in mobile handsets. The CM1421 has component values of 15 pF − 100 W − 15 pF. These devices include ESD protection 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 connected to the filter ports safely dissipate ESD strikes of ±15 kV, exceeding the maximum requirement of the IEC 61000−4−2 international standard.
