Product Description
The CM1683 is an L−C EMI filter array with ESD protection, which integrates two Pi−filters (C−L−C) for the headset speaker. The CM1683 has component values of 100 pF − 3 nH − 100 pF. 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). The ESD diodes connected to the filter ports safely dissipate ESD strikes of ±8 kV, beyond the maximum requirement 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 ±15 kV.
