Murata has announced the availability of the LQW43FT series, a new line of broadband inductors developed for the automotive market. The 1812 size is the world’s smallest inductor for Bias-T circuits that support an inductance range of 10 μH to 22 μH and a high current of 700 mA. It is ideal for vehicle-mounted Power Over Coax (PoC) systems used in Serializer/Deserializer (SerDes) interfaces. Comprised of three models, the series ensures high impedance over a broad range to help reduce the number of required inductors.
With the increased adoption of self-driving applications such as Advanced Driver Assistance Systems (ADAS), the demand for PoC cables capable of carrying both signals and power is also on the rise. To separate the two, multiple inductors are typically combined to form broadband and a high impedance filter. This line leverages Murata’s proprietary material and coil structure technologies to provide superior performance in the low-frequency band up to 100 MHz and can be used in combination with existing solutions to further reduce the number of parts and mounting space required for PoC.
