Product Description
CAMD's 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 com-
ponent values of 15pF-100
-15pF. These devices
include ESD protection diodes on every pin, which pro-
vide a very high level of protection for sensitive elec-
tronic components that may be subjected to
electrostatic discharge (ESD). The ESD diodes con-
nected to the filter ports are designed and character-
ized to safely dissipate ESD strikes of 15kV, beyond
the maximum requirement of the IEC 61000-4-2 inter-
national 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.
This device is particularly well suited for portable elec-
tronics (e.g. wireless handsets, PDAs, notebook com-
puters) 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 Optiguard
TM
coating which results in improved reliability at assem-
bly. The CM1420 and CM1422 are available in space-
saving, low-profile chip-scale packages with optional
lead-free finishing.

Specifications
Note 1: T

=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.
Note 4: Unused pins are left open
Note 5: These parameters are guaranteed by design and characterization.
