Murata expands lineup of high cutoff frequency chip common mode choke coils in 0504-inch size for automotive high-speed differential interfaces.
Murata Manufacturing Co., Ltd. has added a high cutoff frequency*1 product to its lineup of noise suppression components, the 0504-inch size (1.25 x1.0mm) chip common mode choke coils ‘‘DLM11C_HH2 Series’’, suitable for automotive high-speed differential interfaces such as LVDS*2, SerDes*3, USB, and HDMI.
Murata has already started mass production of this product.
In recent years, the automotive market has seen multiple USB ports installed in each vehicle seat as interfaces for connecting smartphones and PCs, and data transfer speeds have increased from conventional USB 2.0 to Gbps-class USB 3.2.
For these differential interfaces, common mode noise suppression is essential, and small common mode choke coils that support high-speed signals are required. In response, Murata developed this product using proprietary lamination technology to reduce high-frequency noise above 7.5 GHz in a compact 0504-inch size.
