3 Channel Headset EMI Filter with ESD Protection

Product Description

Three channels of EMI filtering, two for earpiece  
The CSPEMI205 is a low-pass filter array integrating  
three pi-style filters (C-R-C) that reduce EMI/RFI emis-  
sions while at the same time providing ESD protection.  
This device is custom-designed to interface with the  
headset port on a cellular telephone, and contains two  
different filter values. Each high quality filter provides  
more than 30dB attenuation in the 800-2700 MHz  
range. These pi-style filters support bidirectional filter-  
ing, controlling EMI both to and from the microphone  
and speaker elements. They also support bipolar sig-  
nals, enabling audio signals to pass through without  
distortion.  
speakers and one for a microphone  
Pi-style EMI filters in a capacitor-resistor-capacitor  
(C-R-C) network  
Chip Scale Package features extremely low para-  
sitic inductance for optimum filter performance  
Greater than 30dB relative attenuation in the 800-  
2700MHz range  
+8kV ESD protection on each channel  
(IEC 61000-4-2 Level 4, contact discharge)  
+15kV ESD protection on each channel (HBM)  
8-bump, 1.41mm X 1.45mm footprint  
Chip Scale Package (CSP)

In addition, the CSPEMI205 provides a very high level  
of protection for sensitive electronic components that  
may be subject to electrostatic discharge (ESD). The  
input pins are designed and characterized to safely dis-  
sipate ESD strikes of +8kV, the maximum requirement  
of the IEC 61000-4-2 international standard. Using the  
MIL-STD-883 (Method 3015) specification for Human  
Body Model (HBM) ESD, the device provides protec-  
tion for contact discharges to greater than +15kV.

Lead-free version available  
Applications  
•
EMI filtering and ESD protection for headset micro-  
phone and speaker  
Cellular / Mobile Phones  
Notebooks and Personal Computers  
Handheld PCs / PDAs / Tablets  
Wireless Handsets

The CSPEMI205 is particularly well suited for portable  
electronics (e.g., cellular telephones, PDAs, notebook  
computers) because of its small package format and  
low weight. The CSPEMI205 is available in a space-  
saving, low-profile Chip Scale Package with optional  
lead-free finishing.
