Murata DLM11C_HH2 Choke Coils 2025: Automotive USB 3.2, SerDes Noise Suppression, AEC-Q200 Compliance

Murata has added the DLM11CB120HH2 to its lineup of 0504-inch size (1.25 x 1.0 mm) chip common mode choke coils in the DLM11C_HH2 Series for automotive high-speed differential interfaces including LVDS, SerDes, USB, and HDMI. Mass production has started.

The product reduces high-frequency noise above 7.5 GHz using proprietary lamination technology.

Automotive vehicles install multiple USB ports per seat with data transfer speeds increased to Gbps-class USB 3.2. Common mode noise suppression requires small common mode choke coils that support high-speed signals.
