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. 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.
wireless handsets, PDAs, notebook computers) because of its small
package and easy−to−use pin assignments. In particular, the CM1421
is ideal for EMI filtering and protecting data lines from ESD for the
LCD display in clamshell handsets.
The CM1421 incorporates OptiGuardt coating which results in
improved reliability. The CM1421 is available in space−saving,
low−profile chip scale packages with RoHS−compliant lead−free
finishing.
