PraetorianTM L-C EMI Filter with ESD Protection for Headset Speakers CM1418
Features
* * * * * *
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 117pF/3.0nH/117pF. 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 30kV, which is beyond the maximum requirement of the IEC610004-2 international standard. In accordance with MILSTD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the pins are protected for contact discharges at greater than 30kV. 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 CM1418 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. However, to maximize the power output, the resistance of an EMI filter needs to be as low as possible. The CM1418 addresses this by using a C-L-C based EMI filter with an inductor having less than 0.35 of resistance. The CM1418 comes with OptiGuardTM coating resulting in improved reliability at assembly. The CM1418 is housed in a space saving, low profile Chip Scale Package with RoHS-compliant, lead-free finishing.
