CM1437

4 and 8 Channel EMI Filter Arrays with ESD Protection

Product Description

Features

•

Four and eight channels of EMI filtering with ESD

protection

Greater than 25dB of attenuation from 800MHz

to 3GHz

15kV ESD protection (IEC 61000-4-2, contact

discharge)

California Micro Devices’ CM1437 is an EMI filter array

with ESD protection, which integrates either four or

eight pi filters (C-R-C). The CM1437 has component

values of 7.5pF-200Ω-7.5pF (f = 210MHz). The parts

include ESD protection diodes on every pin, providing

a very high level of protection for sensitive electronic

components that may be subjected to electrostatic dis-

charge (ESD). The ESD diodes connected to the filter

ports safely dissipate ESD strikes of 15kV contact dis-

charge, 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 protected for

contact discharges at greater than 30kV.

30kV ESD protection (MIL-STD-883, Method

3015, HBM)

Fabricated with Centurion™ advanced low capaci-

tance zener process technology

Space saving, low profile 8- and 16-lead 0.4mm

pitch TDFN packages

Lead-free version available

Applications

This device is particularly well-suited for portable elec-

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

ers) because of its small package and easy-to-use pin

assignments. In particular, the CM1437 is ideal for EMI

filtering and protecting data lines from ESD in wireless

handsets.

•

I/O port protection for mobile handsets, notebook

computers, PDAs, etc.

EMI filtering for data ports in cell phones, PDAs, or

notebook computers

EMI filtering for LCD, camera and chip-to-chip data

lines

The CM1437 is available in space-saving, low-profile,

0.4mm pitch, 8- and 16-lead TDFN packages. It is fab-

ricated with California Micro Devices’ Centurion™ pro-

cess and available with optional lead-free finishing.
