2 Channel Headset Microphone EMI Filter with ESD Protection @ ±8kV (IEC61000-4-2 Level 4 Contact Discharge), Chip Scale Package
PRODUCT DESCRIPTION |
|||||||||
|
The CSPEMI202A 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 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. 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 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 CSPEMI202A is particularly well suited for portable electronics (e.g., cellular telephones, PDAs, notebook computers) because of its small package format and low weight. The CSPEMI202A is available in a space-saving, low-profile Chip Scale Package with RoHS compliant lead-free finishing. | |||||||||
