Product Description

California Micro Devices’ CM1419 is an L-C EMI filter

array with ESD protection, which integrates two Pi-

filters (C-L-C) for the headset speaker. The CM1419

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).

connected to the filter ports safely dissipate ESD

strikes 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

contact discharges at greater than

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.

CM1419 is ideal for EMI filtering and protecting

speaker output lines from ESD for the headset speaker

in mobile handsets. Most speakers have impedance of

resistance of an EMI filter needs to be as low as

possible and the CM1419 addresses this by having a

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

than 0.35

The CM1419 is available either uncoated or with Opti-

Guard

assembly. The CM1419 is also available in a space

saving, low profile Chip Scale Package with optional

lead-free finishing.
