ECMF: ST common-mode filters with integrated ESD protection
for high-speed interfaces
ST ECMF technology ensures deep, ultrawide attenuation of common-mode noise at WLAN and Bluetooth frequencies (2.4 to 6 GHz), along with robust (+10 kV) contact discharge ESD protection. Featuring 10.7 GHz bandwidth, these new filters comply with latest high-speed standards, including USB4, HDMI 2.1 and USB 3.2. The devices come in tiny 6- and 10-lead µQFN packages and are optimized for personal electronics and industrial applications.
Key features of ECMF filters
- 10.7 GHz bandwidth for USB4, HDMI 2.1 and USB 3.2 Gen 2
- High common-mode attenuation on WLAN band
- Low serial resistance: 3.0 Ω
- 6- and 10-lead µQFN packages: Thin package
- 0.25 pF line capacitance for a high-speed ESD protection
