CM1418 Praetoriant L-C EMI Filter with ESD Protection for Headset Speakers Product Description The CM1418 is an L−C EMI filter array with ESD protection that integrates two Pi−filters (C−L−C) for a headset speaker. The CM1418 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.
