Murata production office of Co., Ltd. (hereinafter referred to as the company) will provide ultra-small 2012 size (2.0 × 1.2mm) broadband inductor "lqw21ft series" (hereinafter referred to as the product) for vehicle POC (1) interface is commercialized and mass production will begin in May 2021.


POC (power over coax): the way to combine the signal line and power line into a coaxial cable.

In recent years, with the popularity of advanced driving assistance system (ADAS) to realize automatic driving, in order to monitor the surrounding conditions of the car, the car will be equipped with multiple high-definition on-board cameras. Therefore, it is necessary to use multiple cables, so the demand for POC circuits that can transmit signals and power at the same time with one cable is increasing. POC circuit not only processes broadband signals through the circuit processing part, but also separates the signal from the power supply. Therefore, it is necessary to maintain high impedance in the broadband, so multiple inductors are generally used.

This product uses the company's unique ceramic materials and coil structure to achieve ultra-small size (2.0 × 1.2mm) realizes broadband and high impedance, which can reduce the number and installation area of inductors. Thus, the miniaturization of vehicle camera module is realized, which is conducive to the miniaturization and lightweight of electrical appliances.

In the future, the company will also actively develop products to meet the market demand and contribute to the high performance and high functionality of vehicles.
