Overview
CM1411 2-Channel Headset/Speaker EMI Filter Array with ESD Protection Product Description The CM1411 is a dual, low−pass filter array integrating two pi−style filters (C−R−C) that reduce EMI/RFI emissions while 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 35 dB attenuation in the 800 to 2700 MHz range.
These pi−style filters support bidirectional filtering that control EMI both to and from a speaker element.
They also support AC signals with a cutoff frequency of 31 MHz, enabling audio signals to pass through without distortion.
In addition, the CM1411 provides a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD).
The CM1411 can safely dissipate ESD strikes of ±8 kV, the maximum requirement of the IEC 61000−4−2 international standard.
Using the MIL−STD−883 (Method 3015) specification for...
