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. http://onsemi.com WLCSP5 CP SUFFIX CASE 567BA BLOCK DIAGRAM 3 nH A1 FILTER #1 A3 FILTER #1 117 pF 117 pF GND A2 3 nH B1 FILTER #2 B3 FILTER #2 117 pF 117 pF GND B2 MARKING DIAGRAM Features • • • • • • • Two Channels of EMI Filtering ±30 kV ESD Protection (IEC 61000−4−2, Contact Discharge) ±30 kV ESD Protection (HBM) OptiGuardt Coating for Improved Reliability at Assembly Greater than 30 dB of Attenuation at 1 GHz 5−Bump, 1.590 mm X 1.220 mm Footprint Chip Scale Package (CSP) These Devices are Pb−Free and are RoHS Compliant Applications • Headset Speaker Port in Mobile Handsets • I/O Port Protection for Mobile Handsets, Notebook Computers, PDAs etc. CH CH = CM1419−02CP ORDERING INFORMATION Device Package Shipping† CM1419−02CP WLCSP5 (Pb−Free) 3500/Tape & Reel †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specification Brochure, BRD8011/D. • EMI Filtering for Data Ports in Cell Phones, PDAs or Notebook Computers © Semiconductor Components Industries, LLC, 2011 March, 2011 − Rev. 4 1 Publication Order Number: CM1419/D CM1419 PACKAGE/PINOUT DIAGRAMS Table 1.
