ONSEMI CM1420-03CP

LCD EMI Filter Array with
ESD Protection
CM1420-22
Features
Product Description
•
The CM1420 and CM1422 are EMI filter arrays with
ESD protection, which integrate six and eight Pifilters (C-R-C), respectively. The CM1420/22 has
component values of 15pF-100Ω-15pF. 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 ±15kV, 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 ±30kV.

•
•
LCD data lines in clamshell wireless handsets
EMI filtering & ESD protection for high-speed I/O
data ports
Wireless handsets / cell phones
Notebook computers
PDAs / Handheld PCs
EMI filtering for high-speed data lines
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 OptiGuardTM
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.

Note 1: TA=25°C unless otherwise specified.
Note 2: ESD applied to input and output pins with respect to GND, one at a time.
Note 3: Clamping voltage is measured at the opposite side of the EMI filter to the ESD pin. For example, if ESD is applied to Pin
A1, then clamping voltage is measured at Pin C1.
