Product Description

CAMD's CM1402 is an EMI filter array with ESD pro-

tection, which integrates three pi filters (C-R-C) and

two additional channels of ESD protection.

CM1402 has component values of 20pF-47Ω-20pF,

and 20pF-100Ω-20pF. The parts include avalanche-

type ESD diodes on every pin, which provide a very

high level of protection for sensitive electronic compo-

nents 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 ±10kV, beyond the maximum require-

ment 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 pro-

tected for contact discharges at greater than ±25kV.

The ESD diodes on pins A4 and C4 ports are designed

and characterized to safely dissipate ESD strikes of

±10kV, well beyond the maximum requirement of the

IEC 61000-4-2 international standard.

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 for the SIM card slot in mobile handsets.

The CM1402 incorporates Optiguard

results in improved reliability at assembly.The CM1402

is available in a space-saving, low-profile Chip Scale

Package with optional lead-free finishing.
