Commercialization of high frequency inductors for on-board wireless communication equipment

Murata manufacturing office of Co., Ltd. (hereinafter referred to as "the company") has realized the further high precision of ceramic resonator (CERALOCK) frequency, and has commercialized the "cstne-vh5t series" (hereinafter referred to as "the product") of ceramic resonator (CERALOCK) supporting can ※ 1-fd ※ 2. Mass production will begin in April 2021.

Can-fd: abbreviation of can flexible data rate

Due to the electrification of the automobile, the network connecting various functions of the automobile also needs faster communication speed. Can, a communication standard widely used in automobiles, has also been promoted from the existing classic can supporting 500kbps communication capacity to can-fd which can be extended to more than 1Mbps. With the popularization of can-fd, the frequency of clock element generating communication reference clock must also be high-precision. Therefore, the company has successfully developed this product by pursuing further optimization of design and reducing process deviation, and achieved the resonance frequency accuracy required to support can-fd.

As a clock element, the company's ceramic resonator (CERALOCK) has high reliability and robustness and achieves the balance between cost and performance. It has been used in automotive applications by many customers and has sufficient market performance. In the future, the company will continue to expand the product lineup of high-performance and high reliability ceramic resonators (CERALOCK) to contribute to automobile electrification.
