CSPEMI202A  
2 Channel Headset Microphone EMI Filter with ESD Protection  
Features  
Product Description  
•
•
Two channels of EMI filtering  
Pi-style EMI filters in a capacitor-resistor-capacitor  
(C-R-C) network  
The CSPEMI202A is a dual low-pass filter array inte-  
grating two pi-style filters (C-R-C) that reduce EMI/RFI  
emissions while at the same time providing ESD pro-  
tection. This part is custom-designed to interface with a  
microphone port on a cellular telephone or similar  
device. Each high quality filter provides more than  
35dB attenuation in the 800-2700 MHz range. These  
pi-style filters support bidirectional filtering, controlling  
EMI both to and from a microphone element. They also  
support bipolar signals, enabling audio signals to pass  
through without distortion.  
•
•
Greater than 40dB attenuation at 1GHz  
+8kV ESD protection on each channel  
(IEC 61000-4-2 Level 4, contact discharge)  
+15kV ESD protection on each channel (HBM)  
Supports bipolar signals—ideal for  
audio applications  
Chip Scale Package features extremely low  
lead inductance for optimum filter and ESD  
performance  
•
•
•
In addition, the CSPEMI202A provides a very high  
level of protection for sensitive electronic components  
that may be subjected to electrostatic discharge (ESD).  
The input pins are designed and characterized to  
safely dissipate ESD strikes of 8kV, the maximum  
requirement of the IEC 61000-4-2 international stan-  
dard. Using the MIL-STD-883 (Method 3015) specifica-  
tion for Human Body Model (HBM) ESD, the device  
provides protection for contact discharges to greater  
than 15kV.  
•
•
5-bump, 0.950mm X 1.410mm footprint  
Chip Scale Package (CSP)  
Lead-free version available  
Applications  
•
EMI filtering and ESD protection for headset  
microphone ports  
•
•
•
•
•
•
Wireless Handsets  
Handheld PCs / PDAs  
MP3 Players  
Digital Camcorders  
Notebooks  
The CSPEMI202A is particularly well suited for porta-  
ble electronics (e.g., cellular telephones, PDAs, note-  
book computers) because of its small package format  
and low weight. The CSPEMI202A is available in a  
space-saving, low-profile Chip Scale Package with  
optional lead-free finishing.
