Alongside the growing awareness of aspects related to the environment, energy and safety, the “automotive market” has seen more and more electric vehicles (EVs) and hybrid electric vehicles (HEVs) in recent years and, along with this trend, the installation of more and more electrical power systems and secondary batteries and a succession of advances in both the incorporation of electrical operations into various automotive electrical systems and the creation of more and more sophisticated functions for safety systems.

At the same time, consumer demand for connections with external communication systems has been on the rise, and the construction of wireless communication networks and moves to enable the transmission of large volumes of data using in-vehicle LAN systems have gotten underway. By way of responding to these trends, the development of in-vehicle equipment that aims to combine the features and benefits of systems for moving the vehicles and systems for ensuring safety, which is referred to as IVI (in-vehicle infotainment), is being spotlighted.

It is against this kind of backdrop that Murata, ,with a view to meeting the many and varied needs of its customers, is aggressively moving ahead with the development of many kinds of high-reliability EMI-suppressing components and inductors as well as the creation of such products. For some time now, Murata has been providing infotainment-oriented and body control module-oriented products that are intended to be used in the ITS information communication systems and comfort equipment inside vehicles, as well as high-performance and high-reliability products destined for powertrain and safety-oriented applications that are compatible with demanding usage environments.

Incidentally, Murata has decided to support AEC-Q200, an automotive industry standard (see Note 1), which customers all over the world have strongly asked the company to support.
In products that support powertrain and safety applications that typically have a wide and exacting operating temperature range from -55°C to +125°C, Murata continues to provide support for AEC-Q200 as it has done in the past (see Note 2). In addition, it is releasing components that support the AEC-Q200 standard for infotainment-based products as well. In fact, Murata is unveiling two series of new high-frequency inductors—specifically , the LQW series that utilizes a winding process and the LQP series that utilizes photolithography (see Note 3), and it is also offering the LQH series of power inductors.

Components for in-vehicle applications (compliant with AEC-Q200)

Furthermore, as a way of offering greater convenience to its customers when they order automotive specific products, Murata decided to provide different model numbers for each application. As such, the company will be introducing three categories of model numbers: model numbers for “Powertrain/Safety” products that can be used for all automotive electrical equipment applications; model numbers for “Infotainment/Body control module” products that can be used by automotive equipment that do not need to demonstrate a comparatively high reliability such as car audio systems and navigation systems; and model numbers for “General” products that can be used mainly for consumer equipment. (Several examples of these model numbers are given below.)

The model numbers for electrical equipment and automotive devices indicate that the products concerned have the reliability required by the automotive applications and that is typified by compliance with the AEC-Q200 standard. They can be selected and specified on Murata’s website or in its catalogs.
Murata’s aim is to continue to contribute to the “automotive market” in the months and years ahead and to make every effort to develop products that will satisfy its customers.

Note 1: The AEC (Automotive Electronics Council) is an industrial association consisting of the major automakers and major electronic components manufacturers of the United States, and Murata participates in this council as a Technical Committee Member. The council standardizes the tests that form the certification criteria and reliability of electronic components for automotive applications. At present, the AEC-Q standards are being widely used as standards for electronic components for the automotive market. (The AEC-Q100 standard covers ICs and other similar components; the AEC-Q200 standard covers passive components.)

Note 2: A “Murata component that supports the AEC-Q200 standard” is a product for which evaluation tests based on the AEC-Q200 standard (that covers passive components) have been carried out. Contact Murata for more details on such aspects as the specifications of these products and the evaluation test methods used and their results. When placing orders, Murata asks that delivery specification sheets be exchanged.

Note 3: Photolithography is a technique in which the surface of a material coated with a light-sensitive chemical is exposed to light in a pattern (the light-sensitive chemical is exposed to light, causing it to react) so that the exposed parts and non-exposed parts form a pattern, and the material is then submerged in developer to remove the excess chemical. It is mainly used in production of parts such as semiconductor devices, PCBs, printing plates, LCD panels and plasma display panels.
