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-100Ω-15pF.

include ESD protection diodes on every pin, which pro-

vide a very high level of protection for sensitive elec-

tronic

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

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.
