Product Description

California Micro Devices's CM1406 is an EMI filter

array with ESD protection, which integrates 4 pi filters

(C-R-C). The CM1406 has component values of 15pF-

200

on every pin, which provide a very high level of protec-

tion for sensitive electronic components that may be

subjected to electrostatic discharge (ESD). The ESD

diodes connected to the filter ports are designed and

characterized to safely dissipate ESD strikes of ±15kV

contact discharge, twice the specification requirement

of the IEC 61000-4-2, Level 4 international standard.

Using the MIL-STD-883 (Method 3015) specification

for Human Body Model (HBM) ESD, the pins are pro-

tected for contact discharges at greater than ±30kV.

This device is particularly well suited for portable elec-

tronics (e.g. mobile handsets, PDAs, notebook comput-

ers) because of its small package format and easy-to-

use pin assignments.

ideal for EMI filtering and protecting data lines from

ESD in wireless handsets.

The CM1406 is available in a space-saving, low-profile,

8-lead, 2mm x 2mm TDFN package. It is fabricated

with California Micro Devices' Centurion

available with optional lead-free finishing.
