ECMF02-2AMX6

Common Mode Chokes Overview

The ECMF02-2AMX6 is a highly integrated common mode filter and ESD protection device from the ECMF series, manufactured by STMicroelectronics. Designed for surface mount applications in a 6-UFQFN package (1.70mm x 1.50mm x 0.55mm), it suppresses EMI/RFI noise on high-speed differential serial buses. The component supports a maximum current of 200 mA and a voltage of 6V, with a DC resistance of 2.5 Ohms. It provides high common mode attenuation of -34 dB at 900 MHz and -20 dB between 800 MHz and 2.2 GHz, featuring a large bandwidth of 1.7 GHz and compliance with IEC 61000-4-2 Level 4 standards.
