CM1419
Praetoriant L-C EMI Filter
with ESD Protection for
Headset Speakers
Product Description
The CM1419 is an L−C EMI filter array with ESD protection that
integrates two Pi−filters (C−L−C) for a headset speaker. The CM1419
has component values of 117 pF/3.0 nH/117 pF. The parts include
ESD protection diodes on all input/output pins, and provide a very
high level of protection for sensitive electronic components against
possible electrostatic discharge (ESD). The ESD diodes connected to
the filter ports safely dissipate ESD strikes of ±30 kV, which is beyond
the maximum requirement of the IEC61000−4−2 international
standard. In accordance with MIL−STD−883 (Method 3015)
specification for Human Body Model (HBM) ESD, the pins are
protected for contact discharges at greater than ±30 kV.
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 CM1419 is ideal for EMI filtering and protecting speaker output
lines of the headset speaker from ESD in mobile handsets. Most
speakers have an impedance of 8 W. However, to maximize the power
output, the resistance of an EMI filter needs to be as low as possible.
The CM1419 addresses this by using a C−L−C based EMI filter with
an inductor having less than 0.35 W of resistance.
The CM1419 comes with OptiGuardt coating resulting in
improved reliability at assembly. The CM1419 is housed in a space
saving, low profile Chip Scale Package with RoHS−compliant,
lead−free finishing.
