ECMF2-40A100M6Y is an AEC-Q101 qualified automotive-grade integrated common mode filter with ESD protection from STMicroelectronics, supplied in an ultra-compact 6-lead DFN1414 (QFN-6L) tape-and-reel package with 3000 units per reel. Engineered for high-speed differential serial links, it delivers 12.5 GHz differential bandwidth to support MIPI A-PHY, FPD-Link III, GMSL, APIX, USB 3.2, USB4, HDMI 2.0 and HDMI 2.1 protocols, provides -15 dB common mode attenuation at 2.4 GHz and 5.9 GHz to suppress LTE, Wi-Fi, BLE and V2X related EMI/RFI noise, and integrates robust ISO 10605 compliant ESD clamping diodes on the connector side. Featuring less than 70 nA low leakage current, wettable flank package structure and only 1.89 mm² PCB footprint, this 2-line filter replaces discrete common mode chokes plus external ESD arrays, offering superior RF performance and space savings for ADAS, infotainment and automotive high-speed interface designs across -40°C to +125°C operating temperature.
This automotive common mode filter covers these primary application scenarios: EMC filtering and ESD protection for ADAS camera, radar and lidar module SerDes interfaces; high-speed video link noise suppression for FPD-Link III and GMSL automotive display and camera connections; EMI filtering for in-vehicle infotainment HDMI, USB and MIPI display ports; common mode noise reduction for digital instrument cluster and cockpit domain controller high-speed I/O lines; connector-side ESD and surge protection for vehicle external interface ports; differential signal conditioning for automotive sensor modules and communication transceivers; and noise suppression for industrial high-speed differential bus and vision system interfaces.
FAQ
Q: Does ECMF2-40A100M6Y degrade differential signal quality at 10 Gbps?
A: Its 12.5 GHz differential bandwidth introduces minimal insertion loss to differential pairs; place the filter close to the connector for best ESD clamping performance, and route differential traces with controlled impedance and consistent length matching.
