EMI Filter >30dB Flat Style SMD T/R

The CSPEMI205G is a low-pass filter array integrating three pi-style filters (C-R-C) that reduce EMI/RFI emissions 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 pistyle filters support bidirectional filtering, controlling EMI both to and from the microphone and speaker elements. They also support bipolar signals, enabling audio signals to pass through without distortion.

• Integrated microphone and speaker EMI suppression and ESD protection
• Extremely low lead inductance for optimum filter and ESD performance
• Bi-directional diodes protects equally in both directions
