Dual low pass filter array onsemi CM1411-03CP with emi rfi reduction and 8 kV esd protection rating
Product Overview
The CM1411 is a dual, low-pass filter array designed for speaker ports in cellular telephones and similar devices. It integrates two pi-style filters (C-R-C) to reduce EMI/RFI emissions while providing robust Electrostatic Discharge (ESD) protection. Each filter offers over 35 dB attenuation in the 800 to 2700 MHz range and supports bidirectional filtering. With a cutoff frequency of 31 MHz, it passes AC audio signals without distortion. The CM1411 provides high ESD protection, safely dissipating strikes up to 8 kV (IEC 61000-4-2) and 15 kV (Human Body Model). Its compact size, low weight, and OptiGuard coating make it ideal for portable electronics such as cellular telephones, PDAs, and notebook computers. It is available in a space-saving, low-profile Chip Scale Package (CSP) with lead-free finishing.
