CM1420, CM1422
LCD EMI Filter Array with
ESD Protection
Description
The CM1420 and CM1422 are EMI filter arrays with ESD
protection, which integrate six and eight Pi−filters (C−R−C),
respectively. The CM1420/22 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, well beyond 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 format and easy−to−use pin assignments. In particular, the
CM1420/22 is ideal for EMI filtering and protecting data lines from
ESD for the LCD display in clamshell handsets.
The CM1420 and CM1422 incorporate OptiGuardt coating which
results in improved reliability at assembly. The CM1420 and CM1422
are available in space−saving, low−profile chip scale packages with
RoHS compliant lead−free finishing.
