™ L-C EMI Filter with ESD Protection

for Headset Speaker Applications

Features

Product Description

•

2 channels of EMI filtering

30kV ESD protection

California Micro Devices’ CM1418 is an L-C EMI filter

array with ESD protection, which integrates two Pi-

filters (C-L-C) for the headset speaker. The CM1418

has component values of 117pF-3.0nH-117pF. The

parts include ESD protection diodes on all input/output

pins, which provide a very high level of protection for

sensitive electronic components that may be subjected

to electrostatic discharge (ESD). The ESD diodes

connected to the filter ports safely dissipate ESD

(IEC 61000-4-2, contact discharge)

30kV ESD protection (HBM)

OptiGuard™ Coating for improved reliability at

assembly

Greater than 35dB of attenuation at 1GHz

strikes of 30kV, beyond the maximum requirement of

the IEC61000-4-2 international standard. Using the

MIL-STD-883 (Method 3015) specification for Human

Body Model (HBM) ESD, the pins are protected for

Applications

•

contact discharges at greater than 30kV.

Headset Speaker port in mobile handsets

I/O port protection for mobile handsets, notebook

computers, PDAs etc.

EMI filtering for data ports in cell phones, PDAs or

notebook computers.

This device is particularly well suited for portable

electronics (e.g. mobile handsets, PDAs, notebook

computers) because of its small package format and

•

easy-to-use pin assignments.

In particular, the

CM1418 is ideal for EMI filtering and protecting

speaker output lines from ESD for the headset speaker

in mobile handsets. Most speakers have impedance of

8Ω and in order to maximize the power output, the

resistance of an EMI filter needs to be as low as

possible and the CM1418 addresses this by having a

C-L-C based EMI filter where the inductor has less

than 0.35Ω of resistance.

The CM1418 is available either uncoated or with Opti-

Guard™ coating resulting in improved reliability at

assembly. The CM1418 is also available in a space

saving, low profile Chip Scale Package with optional

lead-free finishing.
