Product Description

California Micro Devices’ CM1419 is an L-C EMI filter  
array with ESD protection, which integrates two Pi-  
filters (C-L-C) for the headset speaker. The CM1419  
has component values of 117pF-3.0nH-117pF. 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

Lead-free version available  
strikes of 30kV, 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 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  
CM1419 is ideal for EMI filtering and protecting  
speaker output lines from ESD for the headset speaker  
in mobile handsets. Most speakers have impedance of  
8Ω and in order to maximize the power output, the  
resistance of an EMI filter needs to be as low as  
possible and the CM1419 addresses this by having a  
C-L-C based EMI filter where the inductor has less  
than 0.35Ω of resistance.  
The CM1419 is available either uncoated or with Opti-  
Guard™ coating resulting in improved reliability at  
assembly. The CM1419 is also available in a space  
saving, low profile Chip Scale Package with optional  
lead-free finishing.
