1 / 9 page 2 Channel Headset Speaker EMI Filter with ESD Protection CSPEMI201AG ©2010 SCILLC. All rights reserved. Publication Order Number: April 2010 Rev. 3 CSPEMI201AG/D Features • Two channels of EMI filtering • Pi-style EMI filters in a capacitor-resistor- capacitor (C-R-C) network • Greater than 40dB attenuation at 1GHz • +8kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge) • +15kV ESD protection in each channel (HBM) • Supports AC signals—ideal for audio applications • Extremely low lead inductance for optimum filter and ESD performance • 5-bump, 0.930mm X 1.410mm footprint Chip Scale Package (CSP) • RoHS compliant (lead-free) finishing Applications • EMI filtering and ESD protection for headset speaker ports • Wireless Handsets • Handheld PCs / PDAs • MP3 Players • Digital Camcorders • Notebooks • Desktop PCs Product Description The CSPEMI201AG is a dual low-pass filter array integrating two pi-style filters (C-R-C) that reduce EMI/RFI emissions while at the same time providing ESD protection. This part is custom-designed to interface with a speaker 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 speaker element. They also support bipolar signals with a cutoff frequency of 31MHz, enabling audio signals to pass through without distortion. In addition, the CSPEMI201AG provides a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The CSPEMI201AG can safely dissipate 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 protection for contact discharges to greater than +15kV. The CSPEMI201AG is particularly well-suited for portable electronics (e.g., cellular telephones, PDAs, notebook computers) because of its small package and low weight. The CSPEMI201AG is available in a space-saving, low-profile Chip Scale Package with RoHS compliant lead-free finishing. |
