ECMF02-2HSMX6

Common Mode Chokes Overview

The ECMF02-2HSMX6 is a highly integrated common mode filter designed to suppress EMI/RFI noise on high-speed differential serial buses like USB3.2 transceivers. It provides common mode attenuation of -10 dB at 300 MHz, -20 dB at 2.4 and 5 GHz, and -15 dB from 500 MHz to 6 GHz. The device features ESD protection compliant with IEC 61000-4-2 Level 4 standards (8 kV contact). It operates within a temperature range of -55°C to 125°C, has a maximum DC resistance of 9 ohms, and supports a rated current of 100 mA. The component is housed in a compact 6-UFQFN package measuring 1.60 mm x 1.35 mm x 0.55 mm.
