Array
Product Description
The CM1421 is a multichannel array consisting of four lowpass
filters with integrated ESD protection and four ESDonly 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 6100042 international standard. Using the MILSTD883
(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 wellsuited for portable electronics (e.g.
wireless handsets, PDAs, notebook computers) because of its small
package and easytouse 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 spacesaving,
lowprofile chip scale packages with RoHScompliant leadfree
finishing.
