Product Description

The CM1411 is a dual low-pass filter array integrating

two pi-style filters (C-R-C) that reduce EMI/RFI emis-

sions while at the same time providing ESD protection.

This part is custom-designed to interface with a

speaker port on a cellular telephone or similar device.

Each high quality filter provides more than 35dB atten-

uation in the 800-2700 MHz range. These pi-style fil-

ters support bidirectional filtering, controlling EMI both

to and from a speaker element. They also support AC

signals with a cutoff frequency of 31MHz, enabling

audio signals to pass through without distortion.

In addition, the CM1411 provides a very high level of

protection for sensitive electronic components that may

be subjected to electrostatic discharge (ESD). The

CM1411 can safely dissipate ESD strikes of 8kV, the

maximum requirement of the IEC 61000-4-2 interna-

tional standard. Using the MIL-STD-883 (Method 3015)

specification for Human Body Model (HBM) ESD, the

device provides protection for contact discharges to

greater than 15kV.

The CM1411 is particularly well-suited for portable

electronics (e.g., cellular telephones, PDAs, notebook

computers) because of its small package format and

low weight. The CM1411 incorporates OptiGuard

coating which results in improved reliability at assem-

bly and is available in a space-saving, low-profile Chip

Scale Package with optional lead-free finishing.
