Product Description
The CM1415 is a low-pass filter array integrating three
pi-style filters (C-R-C) that reduce EMI/RFI emissions
while at the same time providing ESD protection. This
device is custom-designed to interface with the head-
set port on a cellular telephone, and contains two dif-
ferent filter values. Each high quality filter provides
more than 30dB attenuation in the 800-2700 MHz
range. These pi-style filters support bidirectional filter-
ing, controlling EMI both to and from the microphone
and speaker elements. They also support bipolar sig-
nals, enabling audio signals to pass through without
distortion.
In addition, the CM1415 provides a very high level of
protection for sensitive electronic components that may
be subject to electrostatic discharge (ESD). The input
pins are designed and characterized to safely dissipate
ESD strikes of
+
8kV, the maximum requirement of the
IEC 61000-4-2 international 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 CM1415 is particularly well suited for portable
electronics (e.g., cellular telephones, PDAs, notebook
computers) because of its small package format and
low weight.
The CM1415 incorporates Optiguard
coating which
results in improved reliability at assembly. The CM1415
is available in a space-saving, low-profile Chip Scale
Package with optional lead-free finishing.
